Interesting thread. When you go out a buy a computer, how long do you expect to use it? How about a car? While I don't think there is a need to "support" the electronic companies, I advocate that you enjoy what is available today.
For me, I would happily buy a PSP, but the only place that rents Blu-Ray discs in my city is inconveniently located. I will wait until my local video rental store stocks them before making a hardware purchase.
