Tablets won't replace anything else... but it's a growing niche... I see them stabilizing at a size between the iPad and the Galaxy Tab and becoming a the next go-to media device.

The Tab is tempting. It's at exactly the right size where you can install it in a car dashboard as a multimedia server / video/music plaer and navigation device. May actually buy one when the prices start going down.

Tablets have the potential to become the all-in-one solution for casual users. People who want to have something laptop-powered, but don't need the form-factor.

I've started using my iPad more now... and I could see a time when I use something similar for meetings (with a keyboard attachment). The biggest hurdle for me is that I'm a power-user. CorelDraw, PhotoShop, Excel, etcetera. (And not just Excel SUM and AVG functions... multi-sheet, hyperlinked, complex databases...).
