Don't get a tablet if you want PC functionality. I have an Asus transformer with the keyboard and it's a very frustrating experience because I'm expecting it to work like a laptop and it just doesn't. The main issue is with Web sites. Casual browsing is ok, but if you want to do online shopping or anything where there are a lot of forms to fill in it's rubbish.
Perhaps the only alternative I would consider for a Laptop is a Chrome Book.
