It looks like the new XPS models have a single trackpad soft-button area (as all new laptops seem to). Have you been able to middle click to paste in X with this configuration?

Thanks!

How's the battery life? Durability? Does the computer sleep/wake up when opening/closing the lid (as expected)?

Note: I have a late 2013 edition, Sputnik 3, there's a newer - 2015 edition which has a much better battery life from what I've read.

On average lasts ~7 hours, less if you're watching a video.

Yes, sleep/wake up is working as expected.

I myself was very impressed when I got the laptop, I didn't expect such beautiful and fine tuned laptop from Dell.

I have a Dell E6320 (Core i3-2310M) from 2011 that I'm running Arch on with a 6 cell battery. The laptop can easily go for 6 hours with WiFi on if you're just editing code or managing some servers via SSH.

Upgraded to 16GB of RAM and an SSD. The only thing I wish was that the screen was higher resolution than 1366x768, but otherwise it's absolutely fantastic for Linux. The dock works so seamlessly it's amazing.

On my 2015 XPS 13 I my power will idle (with wifi/bt on and 50% screen brightness) down to under 5W. You can be more agressive with power savings (I run TLP, but in a pretty middle of the road configuration) and get better use out of it. 10 hours is reasonable use for general work, less if you're compiling while watching netflix of course :)

You really get 10hrs with normal/light usage? A friend of mine got one and doesn't get more than 7 hours with a reasonable light workflow.

I think the difference in time is probably due to FHD vs. touch screen
