I didn't expect the n900 to be a great phone (I consider it a tablet first, a phone second myself). Not to mention considering how Nokia themselves pointed out that it's only step 4 of 5 in building the platform. Step 4 is more for the geek and bleeding edge crowd than your average consumer.

Though I'm not so sure I want step 5 myself, it seems to be too smartphoney and no longer a tablet by that point. Especially given the things they are considering (e.g. DRM systems)
