I haven't used WP7, so don't know if it works well. I hope it is good. More good software and products is always a win for consumers. I think brand loyalty is somewhat overrated. When the first Nokia WP device is released, I doubt if it will be cheap. But the current WP7 devices are becoming very affordable, the LG and Samsung are 200-250 euros (without a contract). So if you are interested in WP7, buying one of those would probably be a better idea. And if WP turns out to be not for you, you can buy the MeeGo/Harmattan or an Android/iphone device in 6-12 months
