totally agree.
We tested tablets over the years at work. Never caught on. We tested the blackberry and now almost every single employee has one. lol
The tablet just isn't as practical and efficient for everyday use as a regular laptop / netbook / pc.
I do see it having a nice role as an auxilary device. Not unlike the nook/kindle.
Would be great to have one tossing around the living room for casual web browsing, ebook reading, doodling and also double as a glorified remote for Windows Media Center or something.
The better option, is the hybrid laptop. One that has a touch screen that can rotate into a tablet. Best of both worlds. Even that hasn't caught on though and I'm not sure why. (see attached)

Regular monitor's with touch screen support are coming down in price too. You can get a 24" for about US$490.00
