I'm not sure I entirely follow you. If I format the data and cache on my phone (basically, reformat the phone's NVRAM containing my info) and then install a clean OS on it (say, Android 2.2), if I avoid logging into Google, I can run it just fine and it works as expected. I even install a bunch of apps without the Android market just fine (I just can't install purchased apps, but that obviously goes without saying). I've actually done this and let it stay that way for a good half a day to see what it's like--and it worked just fine without ANY Google interaction whatsoever. Stability was the least of my any problems I could have even considered. If you intend to use paid apps, you DO need to log in to authorize those purchases, but if you intend to use purely open-sourced apps (like the one I linked to in my last reply to you) or free apps, you don't need the Android Market at all. If I'm misunderstanding the situation, please let me know. I'll definitely agree that life is much easier if you agree to use Google and the Android Market, though, but you aren't forced to use it to have a usable phone with applications.
