Nokia astonished the mobile world (well, more or less since news of this had already been leaked) with its Nokia X1, an Android phone that makes Nokia probably the first mobile manufacturer to have 3 operating systems under control. X1 is a relatively heavy UI change on Android, but as a phone it felt relatively vulgar, indistinguishable from any other Android phone. Below you'll see a few pictures and a video.
We also took some time to check the Nokia Asha, its low end mobile for kind-of developing markets, using the S40 operating system. It's not a full-fledged "smartphone," but it looks like a decent device. See a short video below:
Finally, we played for a few minutes with a Nokia Windows tablet. The Metro UI actually looks very good in high definition screens, as you can see below.
