erm, won't comment on IOS, because its flaws are well known and have already been debated to death. If you're a member of this forum, you've already read it somewhere. As for android, i'm not too impressed by it either. yes its linux kernel based, but with just a lotta java stuff thrown on top, also it too has its stability issues, as i have found. Now WP7 is just getting started and if the way the os is setup to run is indication, it'll just be a competitor for iFools. There isn't anything quite like meego/maemo, and i'm perfectly fine not having a commercially successful OS on my phone, since i care more about its functionality for me versus, whether i see everyone running around with one. I don't necessarily see meego as being a failure unless the competitors you mentioned fix the glaring issue within their own OS's ( lack of multitasking, openess to system customization, crappy widget support, etc ) If they haven't got their act together by the time meego is launched, it could well give it to them hard where the sun doesn't shine.

While my n900 has flaws, none are truly major for me personally. of course i have a small wish that it had more nifty 3d games, but since i have a psp, i'm not really bothered.
