Steve Jobs/Apple just ended the high-def format war by killing both opponents with a single blow. HD rentals right through the Apple TV with no computer needed to sync. HD movies with 5.1 surround sound right to your TV. For $3.99/$4.99. I'm sure they'll eventually let you buy them. If you were thinking about getting a high-def DVD player this year, don't. It'll be OBE in 6 months.
UPDATE: And the new price is only $229!!! I might drop cable and just go internet-only...
