Touch screens are pretty awesome. I really like my Nexus 7. That said, some things are just easier with a keyboard and mouse. I like the idea of the convertible laptops/tablets I'm seeing ads for. I also like that you can revert windows 8 to a "classic" windows presentation pretty easily. Seems the best of both worlds. Touchscreen and Win8 while you're goofing off. If you need to do serious work go back to the keyboard and mouse with Win8 classic presentation.
What's not to like? Progress is going to happen. I heard the same complaints about injection when it first came out. I think things will be just fine.
