My only real complaints about my N900;

1) More RAM.
2) Hardware issues (I didn't have my USB fall out, but I had two of them with bright spots on the LCD, and it got scratched ... time to order a new screen off eBay)
3) There is no number 3
4) Phone call UI was sometimes horribly slow to respond, is this fixed perhaps with the CSSU-thumb? I haven't tested that yet.

Other than really the phone issue, I would have probably stuck with it instead of getting the N9. Much like many others, I would part with my left testicle for a tablet running Maemo 5. I keep telling a co-worker that I hate Android 'cause it doesn't use X11, but he says X11 is so 'heavy' and is one of those guys who thinks wayland is going to make everything so much faster, while he uses a crappy java based UI. Even more amusing is that he pointed out that someone created an 'xorg' program for it. I looked at it, and they can barely run twm with it. It's like being a eunich with a model for a girlfriend.
