My work laptop was recently due for an upgrade, and after careful deliberation, I landed on a Thinkpad T490s. Compared to my previous E570, it was a huge upgrade. The specs are as follows:
- Size : 14 Inch
- Weight : 1.49 KG
- CPU : i7-8665U
- RAM : 16 GB DDR4
- Drive : 256 GB M.2 SSD
Perfect. I am using OpenSuse Leap 15.1 and had absolutely no problems with Wi-fi, Bluetooth or Sleep. I haven't tried to Hibernate, it boots fast enough that I can't see any reason to bother.
I was also given a Thinkpad Dock 2 which works fine out-of-the-box with OpenSuse Leap and Plasma 5.
The laptop is powerful enough to handle all of my daily work, and when I'm forced to use PHPStorm it indexes a LOT faster than my old machine.
The laptop is over 1KG lighter than my previous 15 inch E570, and the screen size difference is barely noticeable. The screen resits glare a lot better than previously, making it easy to see even under harsh office lights.
I haven't typed a lot on the keyboard, since I've become a bit of a mechanical keyboard snob, but the few times I have used it have been a pleasant experience. I honestly think it's the best laptop keyboard I've used. The keys have a lot of travel and a fairly satisfying click.
A brilliant feature of some newer thinkpads is the "ThinkShutter", which is a small sliding cover over the webcam. Some people at my workplace have stickers stuck over their webcams, which looks a bit silly. I don't need to bother, since I can just leave the shutter closed. There's even a small red dot on it so you can easily tell that it's shut.
I haven't had it long enough to do a full "review" of it, and I care more about software than hardware, so that's pretty much the extent of my thoughts on the T490s for now. I can say with certainty that I would recommend this as a linux-powered work machine for someone who wants a light laptop with a great keyboard.
