Its a fair opinion to have, but I feel that anyone who still thinks this way simply hasn't used Windows on a MacBook-priced device in recent history. Are MacBooks better? In many ways, sure, absolutely. Even at Macbook-priced territory, there are wrong machines to buy; shopping for a Mac is far easier. Windows still comes with a lot of ad-driven apps that I won't use (compared to the Mac, which also comes with a ton…

I have yet to find a portable windows machine that doesn’t throttle performance on battery. Weird that no reviewers ever mention it but Macs have nearly no performance difference and they plugged in vs on battery and that’s a huge reason I don’t trust using any Windows laptops on the move.

Does it really matter if it throttles stuff when your other option is using a mac?

Back in highschool they also had those kiosks for adding funds to our student cards, and it would speak out like "Success". I saw someone crashed out the app (probably with a race condition, too) and used the ethernet to download audio files they prepared on the internal servers. The next day the kiosk began to yell hilarious stuff on success and that was hell of a week...

A beautiful example of hacking. Didn’t disable the primary function of the device nor did he profit from a scheme. Just messed with the usage in a humorous way. Bravo.

> Coming from Wintel, the vertical integration of Apple is a dream by comparison You weren't around in the 1990s...

I managed a college Mac computer lab (it was in the school of education, I guess Apple had a lock on schools with those brightly colored iMacs, which is what we had) from 1998-2000 when I was in graduate school. I don’t recall many problems, but maybe I’ve forgotten over the years.

This was middle/high school for me. We were kids and we wanted to break things :) We'd use the debugger to bypass parental controls, edit files to change our MathBlaster scores, poke around apps with ResEdit, etc.

Yeah, we sometimes left the computers in various states of brokenness... but damned if it wasn't educational :) Our teachers eventually caught on, and rather than punishing us, they made us all lab assistants and gave us extra time after school to do LAN parties.

I love reading comments like this, but I admit I'm always pretty curious how the poster ended up in jail. Care to share what your conviction was for?

I should make a clarification: "jail" in the correctional context refers to pre-trial detention, as opposed to "prison" which is post-trial conviction housing. This distinction doesn't happen in the real world :) So, to answer you question, I did 10 years locked up without conviction. No trial yet. Maybe one day?

Wait, what? This wasn't in the US I presume then?

I received a 3 day In School Suspension during the 7th grade for "breaking" one of the computers in the library/school computer lab. What I had done was change the color scheme of the task bar/windows. Made even more ridiculous by the fact that the computers had ephemeral drives and would re-image when they were restarted.

I wrote a dos cli simulator that simulated an empty PC and added it to autoexec.bat. The lab teacher didn’t figure it out and wiped every desktop and reinstalled deleting everything on them. I felt slightly bad. Slightly.

I wish I was that clever in school! The most actual mischievous thing I did was task schedule my boss's computer to change the desktop background to a photoshopped image of my head on Miley Cyrus' body every day on my last day at work.

I would hate to see this. That's essentially what the PC and Android markets are like, which are both full of shitty manufacturers making poorly supported throwaway hardware. The IoT market is even worse. Coming from Wintel, the vertical integration of Apple is a dream by comparison. Never had a single hour of downtime, compared to all the reformats and driver reinstalls and registry hacks and display glitches and su…

Can you recommend a recent Windows laptop? I've used ThinkPads and Surface Books and Alienwares and Razers in the $2k-$3k range and none of them came close to the overall feel of the Mac.

The biggest differentiators for me are performance/watt + battery life. The Mac can keep going for a whole day while the others, even the underpowered Thinkpad with a tiny matte screen and a U-series processor and an extended battery, would die after 2-4 hours. This has consistently been my experience with every Windows laptop I've ever owned in the last 20 years. Even my Intel Macbook had better battery life, and the M1/M2 blows that out of the water. As you said, in another universe. Even while plugged in, the power efficiency means a cool and quiet machine. In two years of using one for work (web dev), I've never heard the fan come on once. Meanwhile my Windows laptops sound like jet engines as soon as the IDE opens, and while building projects, I can't even hear myself think. It's super distracting.

Other issues are screen quality (the ThinkPad matte screens were so, so bad, but I think they do have nicer Dolby Vision ones too), DPI issues (Windows took forever to properly scale the UI up, and once in a while I still run into legacy apps that need manual configuration), sound (the Macbook sounds like proper speakers, not tinny laptop ones), charging (the Surface Book couldn't maintain a charge while gaming, it would just gradually lose power even while plugged in), keyboards (the 17" Alienware was a beast but had an awful keyboard while being nearly 10 lbs), heat (the Razer was straight up dangerous to touch), issues switching between discrete & integrated graphics, etc. Bluetooth and Wifi are totally hit or miss depending on the chipsets. And driver and BIOS and power savings and standby issues all the freaking time. No manufacturer seems to care enough to vertically test their setup after release, so new updates always break something or another. I heard Microsoft recently started manufacturing some of their own chips for their ARM Surfaces; maybe that can help? I dunno, I gave up on them after a series of bad experiences with the Surface line.

I'm not really an Apple fanboy, much as it might sound like it. I use a Google Android phone, a SteelSeries mouse, a Microsoft keyboard, a Monopriced monitor, and Linux at work. I think macOS is pretty annoying sometimes, like its refusal to support the simple keyboard shortcuts for menus that every other OS has. But the Macbook is just so far ahead of any other laptop I've ever used (LAPTOP, not desktop... I still think the Apple desktops are overpriced ripoffs).

Really the only thing I miss about the Wintel world is gaming. These days I have to use GeForce Now or Game Porting Toolkit + Whisky (a GUI), but some games won't work on either. (Edit: Oh, and the glorious ThinkPad keyboards too! Those are still far and away the best, IMO.) Other than that, I feel like my life has gotten so much simpler after the switch, and going to the cafe with a laptop is a joyous experience, not a race to the outlets and hoping to find a table so I don't burn my lap.

I don't video edit either. The only demanding application in my life now is gaming, which is where GFN comes in. But I don't think the M-series is particularly known for raw performance, but rather performance/watt, especially at the medium-end where the computer can keep working for nearly a full day, with no fan and no heat. Hell, I wish they'd make Chromebooks (or Safari kiosk modes) out of these chips, without the macOS bloat. That'd be the perfect travel laptop.

Are you sure about this? My M2 has Low & High Power modes, which affect fan speeds and I think indirectly affects throttling?

>I would hate to see this. Why? You could still buy the real thing. This would not detract anything from your user experience.

What I don't want to see is an ecosystem of shitty accessories and software, like the fragmentation of the Android ecosystem or the race-to-the-bottom of the Wintel world. It means developers have to develop against a bunch of incompatible devices with vastly different specs and chipsets, rush things to market without thorough testing, and stop supporting them soon after release. I've had that experience with all the Wintel laptops I've had, along with all the pre-Nexus/Pixel Androids, and basically every Wifi router and Bluetooth dongle I've ever owned.

The world is overflowing with cheap, crappy electronics and fake reviews. It's nice to have a curated selection sometimes.

In 6th Form we just played Doom95 and Quake in-between classes, in-spite of Group Policy

I get the desire to be compensated for the work that went into reproducing the Guided Access escape, but I have to agree that this is not a security issue. Guided Access controls are in the Accessibility settings. Apple has marketed the feature as one of convenience. And I think a hard reboot, at least this used to be true, will also exit the mode. (Hold power and home button or power and volume button combo.)

For an accessibility feature, it’s extraordinarily inaccessible. Turning it on results in an awful UI involving masking off parts of the screen. No way to invert the selection. Settings aren’t saved. Choosing a password is mandatory (why can’t the normal lock screen password be a default?). And trying to turn on Guided Access at all is far from 100% reliable.

I’ve broken out of it by the extremely complex protocol of swiping up by accident, although not recently. Maybe it’s been fixed.
