Are there any devices that fit the bill of an "anti-laptop"? I despise working on tiny ( It seems silly that most of the volume and weight of the device I carry around daily are totally unused, and that most of the tradeoffs it makes are irrelevant to me, but most small desktop machines are either too large or too slow (to meet a price point, presumably?). None that I know of is designed to operate from a single Thun…

I've kicked around the idea for a while of a baggable computer, in the sense that the components might fit into a satchel or messenger bag, but be connectable to a larger set of I/O devices (keyboard, mouse, display) as needed.

For the past year and a half I've been using the Onyx BOOX Max Lumi e-ink tablet. It's sized large enough at 13" to be a very useful display. As an Android device, it ... suffers many of the limitations of same (see: https://news.ycombinator.com/item?id=32569871>).

But paired with a Real Computer, a keyboard, and a mouse or trackball, plus battery/power supply and maybe external disk storage ... it could be interesting. Those might fit into different pockets of a bag, though this would leave the problem of thermal management (cloth-swathed electronics have poor heat conduction characteristics).

Different components could be swapped out at will. And the device (or its storage) could be paired with a Real Desktop Computer (or work-in-process synched to same or some common storage pool) as needed.

The key constraints for a laptop itself are the fact that the keyboard and screen must accommodate a human's hands and eyes, and provisioning sufficient battery capacity. Busting a few of those constraints for more flexible offerings ... might shake up the concept a bit.

For modern generative computing, web browsing is typically the biggest load. I've used 10--15 y.o. (or older) hardware quite usefully for most of my principle tasks except Web access, which ... is kind of sad on the face of it. Even an older Android tablet runs scripts (generally awk or python) reasonably well. Runtime is about 1/10 the performance of a desktop, possibly worse, but for small working data sets, that's rarely an issue. E.g., I can run awk with effectively the same responsiveness on many thousands of rows of data in either environment. I did find that JSON parsing was notably slower (10--15s on the tablet vs. sub-second response on desktop) for typical workloads, though even that was an issue only in high-repetition development or content-search contexts.

No. It's not a fantasy. The Nokia N900 was amazing . It functioned as a phone with a touchscreen to deliver the experience that had now become the dominant one. But also, by sliding up the screen, it had a fully featured keyboard, and essentially transmogrified into a "pc that fits into your pocket". So you could with a one handed push go from the touchscreen-only experience back to edit documents by using a combinat…

It was amazing at doing.... what? You've just listed a bunch of hardware functionalities without actually saying what you managed to use it for.

at being general purpose computer

Sounds like you're looking for a modern iPad, which is basically just a laptop without the laptop parts.

Except it still has the burden of having a screen

barely though, it mostly has a thin transparent sapphire pane on one side instead of molded plastic.

> Smartphones have been "pocketable PCs" for more than a decade already, but are dumbed down because their inputs and outputs are limited. I wish it was only about the i/o: pocket Bluetooth keyboards, mice and other i/o devices would be just a few bucks away. No, the problem is rather that phones/tablets use crippled dumbed down and tight closed operating systems that offer only a small fraction of the power a real c…

What is stopping you from adapting AOSP to have better keyboard integration? Android has been modified before to adapt to folding screens, tablets and multiple screens.

What particular hardware are you talking about? What good is AOSP when most of the firmware is closed sourced.

All the things you would use a phone for in the early 2010s: * Phone calls * Video calls over XMPP * Text/XMPP messaging * Web browsing * Document editing * Writing and receiving email * Playing music ( it had a built in FM transmitter - how cool was that!) * Setting Alarms * weather widgets * Writing PHP programms * Writing python programms * ssh-ing into servers * gps navigation * take and share pictures * multi-co…

As the owner of a PinePhone with the battery+keyboard...it's hot garbage at most of those.

Pass. I'll take a laptop.

Early 2000's (2002?) there was a pocket PDA device that ran linux and had a workable keyboard - the Sharp Zaurus SL-5000D (developer edition). 32 Mb RAM! Had a JVM installed. Got mine at Java One with a Linksys 802.11b Network Card. Fun (at the time) to boot up linux and SSH into my servers. Processor: StrongARM (206 MHz 32-bit SA-1110) Operating System: Linux 2.4 (Embedix) Memory: 32 MB SDRAM, 16 MB Flash ROM, Displ…

I had one as well. I even installed gcc on the device. No camera but who cares, right? It didn’t need video conferencing as it could do irc with any number of clients. It even had centerim .

It became openzaurus then openembedded and is still alive. Work around to install Wikipedia on an SD card and gutenbrowser make it ver useful except for the 2-3 hour battery life.

I think it is because we require heave duty web browsers needing 8gb of ram, we’ll never return to the pda sized computer days

It doesn't have to only be about safety. I can't use my MBP 13 on the fold out tray of a coach seat. There are times where a less conspicuous device comes in handy.

A 7" tablet fits into a large pants pocket. A 13" laptop does not.

I used to have a VAIO P series laptop - https://en.wikipedia.org/wiki/Sony_Vaio_P_series It could just about fit in the back pocket of my jeans and had a sim card slot for mobile connectivity, if I remember correctly. It was a really nice little laptop. Not going to be rendering any 3d models on it, but great for basic internet and office work.

Did it fit on your pocket? There were meme for the PR https://www.engadget.com/2009-01-12-vaio-p-doesnt-have-nothi...

Maybe we can't? I have been wondering about that for quite some time now. We have been talking about ubiquitous computing for a long time, but instead of doing that, it seems we have settled on using smartphones for everything, retiring specialized or underpowered devices in their favor, even if they are just 60% as good as their predecessors. When a company tries to build something in this niche, it seems we need as…

In the 90s the market was new and fresh and nobody really knew what would sell, so people were gambling on many variations of product. Now we know what sells, and it's an iPhone or an iPhone wannabe. Nobody wants to spend tens of thousands of dollars on something that isn't a phone, so nobody does the development to mass-produce these items. Notice how phones were wildly insanely weird before the iPhone and very quic…

Not "nobody". Just not as many people as the other thing.
