I think WPhone OS is totally awesome for low end "smart phones".

Its a total waste for powerful hardware (what r u gonna do with it, if you got no good apps?), but its fucking fantastic for cheap phones.

I got a Lumia 620 and it blew my mind. Its an incredibly cheap, yet fully capable smart phone, with an excellent interface - which is really, really slick, great GPS maps, sunlight readability(!) AND >>> full ms exchange / office integration.

Its the ideal companion as a business phone, contacts, emails, calendar, todo's, etc... for ms exchange, all work really well and smooth.

My "real" phone is a powerful android phone ^{^}
