Just bought a Acer Aspire V5 with touchscreen. I haven't played around too much with it (was mainly purchased for my wife). When shopping, I was looking for 1 of 2 things... either a laptop with Windows 7 and an SSD or, if I couldn't find one decently priced, then one with Windows 8 and a touchscreen.
It should be noted that just because it has it, you don't have to use the touchscreen, but for moving around the modern UI on the laptop, I prefer it to using the touchpad on the thing. I've never used Windows 8 before, so there was definitely a learning curve to it. Still haven't quite figured it all out yet.
I finally understand what people meant when they said MS was transitioning to a walled garden approach. The modern UI side of the OS just seemed limited. For instance when my wife was trying to print some information off a web page, she couldn't choose a range of pages (ie. pages 3-6). It was all the pages or none of them. We had to switch over to the desktop version of IE in order to have that functionality. Seems redundant to have 2 separate versions of IE running in one OS.
