But the tablets ARE only meant to be used for browsing the internet.
That's how they're advertised, as being for things like websites, blogs, e-mail etc. That's why they're called "internet tablets", they're meant for using internet services. They're NOT meant to be laptops or PDAs or UMPCs.
Watch the official adverts and they don't even mention installing additional applications or anything that requires technical knowledge.
If your PC is working fine then it can be as userfriendly, but when something goes wrong the tablet is usually easier to fix, and there's a lot less that can go wrong on a tablet.
I say this out of experience with the relative I recommended the tablet to that led to the founding of the Internet Tablet School site. He was always having troubles with settings and error messages on Windows and Macintosh, but on the tablets there weren't really any problems after the first set up.
