Microsoft's tiled Windows Phone interface is clever, but it's really how well the device interacts with Windows programs that will ultimately dictate if wireless customers trade in their Androids and iPhones for the Lumia, which is competitively priced at $100.
It's hard to bet against Microsoft, but the real challenge relates to the question of where Microsoft fits in against the competition:
1. As an open source platform, Android is popular with handset manufacturers because it doesn't cost them anything to offer slick devices that play right into the app-rich Android ecosystem.
2. The iPhones have the high end of the market cornered.
3. Companies used to flock to BlackBerry for email and security purposes, but now corporate IT departments are caving to worker demands to embrace the more popular Android and iPhone platforms.
In short, it won't be easy for Microsoft to stand out, but you can't blame it for trying.
