Blood. It's nature's lube
I could never reasonably decide to buy one for $300, there are better places to put that money (like buying video games or computer upgrades or hookers, or just saving it).
I'd suggest you get a cheaper one, video playback is probably a nice feature and all, but how often will you really NEED to use it? It sounds like one of those things you'd use a lot when it's new just because you can, but once its novelty wore off it's probably just another glossy but unnecessary feature implimented just so they can charge more. I could see needing it if you fly a lot, or if you're on the road or out of the house a lot in a place where a TV isn't available and you have enough free time to watch videos. But other than that I think it's too much money to justify spending on such a novelty.
So, if you think you'd really get some good use out of it, the video playback feature, that is, than go for it. Otherwise, buy a cheaper one and save some money.
