Only 16 gigs of RAM? Why do companies still hold that limit in 2018? I was hoping for 32 gigs back in 2015.

Intel needs to ship Cannon Lake before they'll have support for LPDDR4. That was expected to ship in 2016 but is now sometime in the first half of 2018.

I've had so many problems with my XPS 13 that I bought in 2016 that I will never buy another one. Killer WiFi card was utter crap, laptop has issues going to sleep and waking up when closing the lid (sometimes it would hang on the the dell screen when trying to wake up and never recover), etc. Purely anecdotal, but a hard pass for me. Lenovo is my new laptop brand of choice.

I have a kaby lake xps 13 and have never seen it fail to resume (and I suspend/resume very frequently). There is a really annoying bug between the dell bios and the intel pstate driver where it often gets stuck at a super low cpu frequency after resume though :(

The Killer wifi has been reliable for me, IMO atheros or intel is always a good choice for wifi on linux

IMO, it does not make sense to buy any of those new models: whether it's Dell, HP, or else--before we see models with 32Gb of RAM. It's been told here over and over since 2016 when first Touchbar MacBook got released. It's 2018 and all of us, including manufacturers, are locked with 16GB of RAM and those upgrades look like a joke. Within last month I noticed myötähäpeä when someone asks me for laptop advice. Hopefull…

I've been using an HP zBook for a while now with 32GB of RAM and it could be configured up to 64 GB of RAM. ECC is an option too on it.

Note that 32GB is available if you move up to 15": https://bartongeorge.io/2017/01/09/welcome-the-new-ubuntu-ba...

Intel chips don't support LPDDR4

the XPS 15 is available with 32gb

The XPS 15 doesn't appear to use low-power DDR4 memory - it's valid to trade battery life for performance but most users buy the former.

Should I hold off on buying a computer until this spectre and meltdown issues are fixed?

That will take a year no?

A year would be a fairly aggressive timeline. Ultimately SPECTRE et al are just exemplars of a class of exploit that I'm not sure anybody has seriously thought about how to deal with systematically. I've done the "daydream off for five minutes and try to solve the problem" a couple of times and I generally get to "let's design a new CPU from the ground up, using an entirely new set of formalisms"[1] pretty quickly, which is, ah, let's say, not a one-year effort to get it into customer hands. Timing attacks suck.

[1]: By this I mean that in general, our formal systems dump time as a consideration as quickly as they can. The systems designing the CPUs themselves don't, of course, because time is a big deal in making a modern CPU work at all, but otherwise, we dump it as a consideration as quickly as we can, for lots of reasons, like not overspecifying a system and overconstraining it, and because it's really, really hard to keep track of time, and generally doesn't bring value commensurate with that complexity. Having built our stack of software and formalisms without very much thought about tracking time precisely, we generally only once at the very end recapture some time information, when we care, via O() analysis, and generally via the use of a whole crapton of explicitly-approximated values, which for what we care about is almost always good enough.... until timing attacks. Timing attacks suck. I think we're just barely beginning to come to grips with how much they suck.

Which lenovo product would you recommend for a linux laptop?

Not 100% sure but mostly due to battery life, the more ram you have, the more power you use. 32 gigs probably shaves hour or so off the battery (don't know for sure) and that might be the reason.

I use my laptop almost always with a power supply (either home or office) so I would happily trade some battery life for more RAM.

Then a 13" ultrabook is probably not the right thing for you; search for "mobile workstation" on any of the major manufacturers sites and you'll find ones that can be configured up to 64GB of ram.

That is from June, this is the latest from December: http://en.community.dell.com/techcenter/os-applications/f/46... A motherboard change and a BIOS update (2.4.2) are supposed to lower the noise as much as they can, while still deeming it "working within specification". Users report the 2.4.2 update didn't help much or even made it worse.

This update (without motherboard change) did help by making the fans run less often, which doesn't seem to be causing overheating issues or me
