What I am waiting for is an integration of everything into one small device.
Add to it blue tooth to one of the screen glasses to project right in front of me.
So I will no longer have a lap top, PDA, camera, and Phone. But one do hickey (technical term) that does it all.
Other than that I like paper and like being able to walk into my office and grab a book off the shelf and look up what I want.
Some of the electronic files are just too big to qquickly dig through.
Sounds like you're looking for something like a Droid X. Phone, it's got a bluetooth, full web browser, camera, app support (so it'll do anything the "PDA's" of old would do, and much more), as well as full media support for music, and movies. You can get both Kindle and Nook e-reader apps for it too, like any Android phone (Kindle and Nook are devices, but you can get the apps to access your books bought through them on other devices as well).
It, and many of the touch-screen smartphones really do do it all these days. Heck I like to goof around a bit on my guitar, and I no longer need to even carry around a tuner. I can bring up my tuning app on my phone (which naturally has a microphone), and then strum and adjust each string using the tuning app to tune it.
Only downside about using the phone is that the screen is smaller. That's kinda necessary though. Make it too big and you reduce portability (as well as make it cumbersome to hold up to your ear). Small screen makes web browsing a bit less fun. You certainly CAN do it (and I've checked this forum from both my phone and my iPod Touch several times), but it's not a pleasant experience. The new tablets like the iPad have larger screens (7" to 10"), and make much better web browsers. They pretty much do all of it EXCEPT for phone calls, again, because you really just can't take an iPad and hold it to your ear. Due to it's screen it also doesn't get the same battery life as a dedicated e-book reader as well (though you works well while it does have power

). You can expect about 17 hours of usage time per charge out of an iPad. You can get weeks out of a Kindle (or a Nook - pretty much any of them that use an e-ink screen instead of an LCD).
I think we'll have that gap in screen size for the foreseeable future, mostly because it's not a technological or engineering limitation. For one usage mode you WANT a small screen. For another, you want a larger screen. You can't have a screen that's both large and small at the same time.
If you want something that literally "does it all" though, a modern touchscreen iPhone or Android device really is hard to beat. I still want my full computer, but I know a few people who just carry the phone now, and apparently it's VERY common in places like Japan for people to just carry a smartphone and not even own a desktop or laptop.
