In the context of phones, I'd say yes.
based on what I've seen, Windows Phones, and more recent Windows versions, work quite well on mobile platforms and devices. (I'm of the mind that they work fine with keyboard and mouse too, but some feel there has been a compromise in that regard.). And it is a worthy competitor to Android and even iOS in terms of what Windows on smartphones brings to the table.
One may wonder why, then, I think Android is better, after singing the praises for Windows phone. Well, for all the good design that went into Windows running on mobile devices, it is still only about on par with Android. The thing that breaks the tie is the fact that Android actually has "apps" (I hate that word) that you can use.
of course, all this is coming from somebody who has never owned a smartphone or mobile phone before, anyway (At least until the one I bought last week arrives)
