Read this comprehensive review at engadget.com: What we've been presented with here doesn't exactly feel like a complete mobile operating system in many ways. Some parts of Windows Phone 7 are more like a wireframe -- an interesting design study, an example of what a next-gen phone platform could be. That's both good and bad. On one side, we're still really excited by the prospect of Metro as a viable, clean-slate approach to the mobile user experience, and there are lots of smart moves being made that could lead to greatness. On the other side, Microsoft has to turn this into a viable retail product that can hang with the fiercest competition in the history of the cellphone in just a few months' time, and there are some serious issues that need to be addressed. Frankly, it's a little scary.
By any measure, Microsoft's got its back against the wall in the mobile game, and becoming competitive quickly is vital to the company's success -- and in that regard, we understand why they've been so adamant about getting Windows Phone 7 on shelves in time for Holiday 2010. The thing is, putting out a product that's half-baked risks alienating early adopters at the worst possible time, especially considering that we see a clear-cut (and pretty painless) path to fixing the most egregious shortcomings. Seriously, if the WP7 team put their heads down and added a clipboard and some rudimentary multitasking, Microsoft could have an exceptionally solid version-one product in Windows Phone 7 -- especially when coupled with the company's fierce outreach to developers.
Of course, that's a big "if" -- the clock is ticking on Windows Phone 7, and the industry has already proven that it won't wait around for companies to play catch-up. It's not about lapping the competition at this point, it's about just being in the race -- and if Microsoft doesn't know that by now, it may already be too late. Read full review
