Are you sure? So if I buy a WM7-phone in e.g. France and it comes with French language, I may change the system language to English if I want to? You see, that was one of my major issues with WM 6.5 and I would hate to experience that again.
What makes you think I don't know how to keep up with newer versions, and why is it even relevant? WM 6.5 probably had its improvements over WM 6.1, which was better than WM 6, which was even better than WM 5, and so on. WM 7 can't be that much better than 6.5, at least I won't assume it is until I have tried it myself.
When I got my iPhone, it was before WM 7 came out, and I have no reason to even try WM again until my iPhone is worn out and I have to get a new phone anyway.
Common sense dictates that one should not bad mouth a product using an old OS, giving the impression that Windows 7 7.5 out now is bad, but to read up on the newest version first to see what others have said, than post or not post at all. No one is going to buy the old OS windows that you mentioned, but WM 7 so your experience with 6.5 is mute
