I too agree with the "new technology" constant. In my experiences: waiting for the new model or version to come out always seems to cost me more. Bigger, better, newer version=more expensive than the past current, now older model. The worst part about it is that I waited to spend more money for not much of an upgrade. Some upgrades and new versions are well worth the wait and some aren't. Nobody will know until it is too late...or would that be just in time.
BTW wife bought PS3 for my Christmas present(so I didn't ponder). I love it. The audio and video rock!
