I'm also confused by the form factor. Presumably, one of the reasons it's so (comparatively) expensive is that it's an extremely small device (so a lot of R&D money has gone into it with lots of custom components). But does that really add much value for a gaming console? If it's going to sit in your living room, would anyone really care if it was, say, twice as big? Or a different shape?

And for all the talk of a modular, upgradable design, it looks like you more or less have to dismantle the entire thing to swap out components. In fact, it looks harder than doing so for a regular PC.
