Read the original post and decided to reply. I was a tablet skeptic (of sorts) but I was fortunate enough to get to borrow one and try it out before I bought it. I tried a tablet for a few weeks and decided that it did, indeed simplify my baggage.
I use some 13-odd productivity apps. on my tablet. (Brand-neutral tablet discussion.) Evernote, box.net, dropbox, Office-apps, text editor, eBooks (Kindle, Nook, Stanza), Readdle (make PDFs from web), iAnnotate (to markup PDF files), ToDo (syncs w/ Toodledo), and iSSH. (iSSH is certainly not preferred over a laptop, though.) These tools really do allow me to leave my laptop at home because my main use is document review and notes. I use my tablet for reading technical documents in PDF format. I have literally gotten rid of handling a large binder by using the tablet. Yes, I could have done the same with a laptop, and I did try that for awhile, but the tablet is so much easier. Plus, the tablet is only 1.5 lbs, so my messenger bag is much lighter than it was -- I don't even bother to carry a charger anymore. The eReaders mean I don't have to tote a separate book anymore either.
I prefer tablet apps that allow me to keep a local copy but save a copy to the internet. Keeps me out of trouble in case I ever drop the device out a car window. Calendar, email, and the browser are also quite convenient on the tablet, as are all the social apps. Instant-on is a great feature.
The tablet doesn't replace my laptop, but it does complement it in that I don't have to tote around such a large device during the day or while sitting on a bench or in a cafe. I also find that the tablet is less sun-sensitive than a laptop. It's not a e-Ink, though.
That's how I use it. YMMV. I'm not trying to compile code on it or edit photos or movies -- I don't do any of that stuff on a tablet. I didn't care to jailbreak it or root it -- if I wanted to do that I'd just buy a Color Nook. I read, take notes, adjust my calendar, and handle email on it. I don't actually have any games on my tablet.
Also use it for cooking! :^) Forgot about that. It's just a convenience.
If I had to choose between living out of ONLY a tablet or a laptop, I'd pick the laptop, though. At least, for the current generation. The tablet is all about 'easier.'
