Give me root access, a terminal, full multitasking and a handful of expert users that compile stuff to it. Then I can run things like Pidgin and not have it swapped out after five minutes like everything on my Galaxy Tab. Give me better contact/IM integration than Android, which the N900 already had. Those things alone will be a powertool. Add stuff like excellent DLNA support, and I'll never regret not having Google Market/Play. Top it off with the ability to hook up a DVD as a share, and play my legally bought movies unripped like I can on an Ubuntu laptop, and I can't think of more to ask for.

Oh well, I bet Flash is always going to be an issue.
