You know these type of conversations is always very subjective. Some people seem to have constant problems with their phones and others have none. I can say I have NO hardware issues at all. Great phone. as for the OS, I like it FAR more than iOS and Android. That is not to say those OS's are not without their good points. But for me, it's all about having a phone that does what I want, works well and above all else NOT being bored. iPhone bores me to death with all the stupid little icons and one phone to choose from. Android is far more interesting but is now getting just a little crazy with the multitude of settings on some of the phones. Also, given the nature of the open system, you are almost constantly having to fine tune things and hunt down apps that just weren't designed right or just chose not to work right on your particular phone. As for the Windows Phone, I find the UI very smooth and refreshing. Classic and simple yet providing useful information in the form of live tiles. The ability to size, add/delete things to the home screen gives you the feeling of making it uniquely yours. Certainly there are aspects of some of the software that I would improve but overall, it satisfies me far more than anything else out there although Blackberry 10 might prove intresting. Still, this phone gives me seemless syncronization with my desktop and allows me to easily share with my husband who up until now always managed to miss or lose track of those things. Now I put them in the Family Room and no problem. Life Is Good.
