I know these things *can* be done without the dock, but nowhere near the ease that they can be done with the dock... Trust me, I've tried! The dock just makes everything that much easier... It's completely changes how useful the tablet really is. There is *no way* that you can enter text as quickly and easily with a stylus as you can with a keyboard - period.
I guess it all boils down to what you use your tablet for. I take a *lot* of notes at work and it would be a disaster without the dock (I simply wouln't use it at work without the dock - it just wouldn't make much sense). If you just use it casually to play games and surf the web, I can see the dock not being needed, but if you do any kind of emailing or note-taking (or even posting on XDA), the dock just makes it that much faster and easier. To be honest, I personally leave it docked even while playing a lot of games!
