You are right it's not a phone it's a tablet but didn't want to create confusion.
I know I'll get blasted for being a troll or whatever, but I've owned this device since it was available in the US (December, 2009). The N900 is not good at being a phone OR a tablet. At best, it's a fun toy to hack around on. If you're serious about getting a smartphone/tablet/phone, look elsewhere. When people ask me if I like the N900, I always say "It's a fun hobby!" and advise against them getting one unless they have the time to deal with the many quirks it has.
