I hate it, and I don't like that all the new computers come with it and if you want to downgrade, then you void your warranty. It's ridiculous. I thought I'd get used to it, but after about 4-5 months, I still find myself getting irritated with it. There are a lot less programs with it too. As Sammi mentioned, it would be nice as a touch screen, but if I wanted that option, I'd buy a tablet. I saw it in action on a computer the store had that was touch screen, but I just don't like the idea of a touch screen unless it's a phone, e-reader, or tablet device.
I don't like having to drag my mouse to the edge of the screen to access the Start menu, then go to it to open Word or some other program, then go back to my desktop. I liked being able to stay on the desktop, click Start in the corner and have direct access to all my programs.
I haven't even tried using this webcam yet because it will probably bug me to no end.
I honestly don't think I'll ever like it, but it looks like I'm S.O.L because they told me at the store that there were a few in the store with Windows 7 but now you will only be able to get a new computer with Windows 8.
