Is this supposed to have anything at all to do with this thread or is it just a random insult?
As to the OP, tablets are OK if you just treat them as a new device and not a replacement for your other devices.
As a purchase, if youve already got a desktop/decent laptop and a smartphone, then they arent too bad. If you dont own those I'd get them first.
That's my problem with tablets. According to the marketing, they'll replace laptops, desktop computers, TVs and pretty much everything else. Microsoft is forcing a touch/tablet UI on to desktop users, because it's "the future" and we'll just have to get used to it. Apple is doing the same to OSX, but at least it's more subtle and elegant. What they don't seem to understand is that people will still want a 24" display and a 42" TV.
Also, while touch is "cool", it's actually not the best interface in many situations. The big advantage is gestures and swipes that you can't do with a mouse, but there are many disadvantages. Your fingers are too fat for any kind of precision, which is why everything has to be *huge*. Compare this to the mouse - a good, high-DPI mouse gives you 1-pixel accuracy.
It will never work with a large display because it's not scalable like a mouse - you can use the same size mouse pad regardless of whether you're working with a 12" screen or a 27" one. This is not true with touch - if you're working with multiple, large displays, it's would be totally ridiculous to use touch because you'd have to move your arms so much in order to reach everywhere on the displays.
