I have a 2013 Thinkpad so I know about the new keys and I don't mind them at all. And I really like that they've gotten rid of the trackpad completely on the new models since I hate trackpads even more than a separate mouse.
But I do rest my palms on the area beside the trackpad. Looking at the new models that area seems like it might be a bit short. I'm not sure where my wrists would rest there and I fear they may be in some in between zone not completely on the keyboard and not completely off of it. That would probably be annoying. Hopefully that's not the case. I'm tempted to order one of these just to find out whether I find them okay or not. If I don't, I'll have to scour the internet for older models and buy a few. Thanks for the heads-up :)
