Timely analysis of pros/cons  

Once again, Netflix has rewritten the rules — this time, of the online movie-rental game. The company has done away with expiration dates, copy protection and multi-megabyte downloads. That’s because you don’t actually download any of Netflix’s movies; instead, they “stream” in real time from the Internet to your computer. (This advantage comes with a key disadvantage: you must be connected to the Internet. Wireless hot spots at airports and hotels are fair game, but movies can’t be carried around on a laptop.)
