I'm also interested in Meego though as a Java-based Linux-software-incompatible desktop like Android is isn't my idea of fun. Now all we need is everyone to jump onto a single standardized versatile true solution package manager so it's even easier to run the same apps you do on your Linux desktop on your Linux phone as well. Pretty obvious durr idea for freedom and making Linux 1000 times awesomer.
The form factor just sucks for most tasks where you're relaxing or wanting to get real work done. Holding something up while trying to also do work on it is just a nightmare.
Quite simply, laptops/netbooks can be used as a desktop replacement if you want. Tablets can't and are more like a big phone form factor, and I don't need two phones.
