Ageed, except that PAL (768x576), and even worse NTSC (720x480), isn't even regular resolution, so lets leave HD alone. I wall rather call it non-usable, at least for purposes involving text (for writing videos, it's so-so).

The fun thing about using so-called USB-VGA, is that - besides being able to use VGA at all - image processing is done on card itself, with some (varying between cards) aid from CPU. Basically, they're simple, external graphic cards. That mean, we can - using good USB VGA - get 1680x1050 (or higher) resolution from our n900, without much affect on performance. Heck, personally I would be crazily happy penguin with 1024x600 on external screen through VGA...
