Engadget is right - years ago the mobile industry was dominated when it came down to units moved, profits made but now it's future success is defined by the number of apps, games and developers attached to each competing platform.
Nokia last week announced 400, 000 new developers over the last year. Microsoft may only have 15, 000 - but it's quality over quantity, right?
Microsoft have said that having the 15, 000 developers for Windows Phone "signals their intent to bring exciting content to Windows Phone". What I find funny, is what company would say the opposite? "We are bringing 15, 000 developers for things aren't exciting - you won't like them.
Let's hope that they do bring exciting content - I used one of the HTC Mozart handsets last night and it is actually surprising cool. If I didn't have an Android I'd definitely be looking at tapping the Windows Phone 7.
Oh, but it'd need Angry Birds first.
