Actually I think it's going to change how we work just as much. Think about it. iPad 3G + HTML 5 business web apps? No more software to install, constant connectivity, dynamic touch driven interfaces,etc. If that's not some Jetsons shit, then I don't know what is.
Exactly. Enterprise IT doesn't want "computers" for it's employees. They spend so much time locking down, reconfiguring, managing etc. PC's in the workplace. Build the few in house apps employees need as iPad apps or web pages and freakin be done.
iPad with a keyboard and maybe bigger screen will be the netPC et al, done right.
