Nobody except Apple knows yet. We will probably know at launch day. My bet is 512MB.

I don't really remember, but I know I donated at least $50 (or a little above), since that was my Christmas gift to my parents. They always say they wanted nice kids, so I donated 300NOK to Red Cross and got a nice poster as a proof that I've been a nice kid. Red Cross Norway nailed that one, probably got more donations this Christmas than ever before.

A more likely explanation is that Asus pays just $6 per XP netbook license. They will refund their expense, not the cost of an OEM licence at Amazon.

Personally I can hear the difference of 160kbps Vorbis and 320Kbps Vorbis, and any mp3 compared to high bitrate vorbis or lossless. That said, Spotify with 320kbps Vorbis has finally reached the point where I consider it worth paying for it as a streaming service. In most cases I can't differentiate between 320kbps Vorbis and Apple Lossless, which is my default ripping format.

The few times I really want to listen to high-quality music, I put on my Sennheiser headset or turn on my toslink-connected hifi system, and play SACDs directly or lossless rips on my Mac.
