smart phone operating system?

well for phone i think its symbian, i see a lot of corrupted files in windows mobiles. well apple also but a trade off is customization.

as regards stability and functionalities as well i like some mobile os based on linux kernel as the old maemo for nokai for example or now i think that palm webos cna be good!!Surely it will come out soon a new linux os called meego designed by nokia nd intel together and so it seemed really good from this point of view in the alpha version we will see for the stable one.

I like to use Windows mobile system and I have used it for years. I have collected many software and games and this is why I don't really want to change another mobile phone operating system. I love China

That is really a good question as I use a windows mobile phone. I can't say how stable it is, as it is hard to tell, but I haven't had all that many problems with it. It does load slow though when I first turn the phone on, and it is bad for that, but otherwise, I really haven't found it to be all that bad. Now, when it comes to android, I don't know anything about it, as I have never used one of those3. Now, my daughter has an HTc aeris and she likes it a lot especially the apps she can put on her phone. Now, I do have a marketplace on my phone, where I can put lots of apps on it, but I haven't really done all tha much with it as far as the apps are cocerned. I like my phone, as I can do quite a bit with it, and that is why I bought it. Take care, and happy mylotting.

Apples iPhone coming from a market that is very strictly controlled there is no room for errors so for stability the iPhone os is the best. For apps I would say android is probably would be the best because no one controls the apps that are allowed on their market and it is all on an opensource os. Speed doesn't depend on the os it all depends on the hardware... so i can't tell you which is better for speed. I am thinking about android more then ever before and will be trying it soon.

Windows mobile 6 for sure because of easy connectivity with windows pc and lots of additional softwares and features are available. I prefer Windows Mobile because it has more power, i.e. it can do many more things. I am a user of Windows mobile and while it isn't as stable or simple to use as BlackBerry, it offers better web browsing, better 3rd application support, more freedom with the software, a touchscreen if you like that, a much more computer like experience, better PDA features.
