Although great, not for everyone

First of all, if you wanted something that will play all your MP3s and movies, you should be looking for a video Ipod. Please don't bash this item if that's all you wanted. This is not called the PlayStation Portable for nothing. It is a gaming device first. Now for my review. I waited nearly a year for the silly Ebayers to calm down and went online to get one. Although I got the white one, the only difference between the two is the regional coding (but I never cared for the movies anyway) and the fact that the X and O button functions are reversed on many games. The unit is heavy but it doesn't detract from the gaming experience. The screen is so sweet. The ads do no justice. It's a very nice screen. You will be impressed when playing games like GTA: Liberty City or Tomb Raider Anniversary. If you have a Playstation 3, the menu layout functions on it were taken from the PSP so you won't be in the dark about how it works. The speakers are not good. I always use Philips earbuds and the sound is DRASTICALLY improved. The screen bit rate is excellent. There is never any video lag even with high speed games like TRA. It uses the Memory Stick Pro Duo to save the games but that's no longer an issue. The prices on that format keep dropping. The Wi Fi is VERY fast. It put my Tmobile MDA to shame. I bought mine from a wholesaler in Japan and he tossed in three free games and a car charger with it so I saved about $99. The price has now dropped to only $179 but it's still the best portable gaming system on the market. I can't review its movie playback functions because I don't care for the UMD format. The movies are overpriced anyway. Buy a portable DVD player instead so you don't have to pay $30 for a silly movie. The battery life is bad but Sony released a high capacity battery later on so that problem has been ironed out. I get cramped hands easily so you might want to find Playstation control pad covers that snap on both ends. The bad thing is that they're almost impossible to find. This is not a great gaming device for people with carpal tunnel syndrome. It will make your wrists hurt after only 20 minutes of game play. I VEHEMENTLY recommend a spare battery OR car charger. You'll be surprised how quickly you wear down the battery. A high capacity battery is a wise investment. Overall, I wouldn't worry about the PSP Slim as it offers nothing new but a flatter body and a SLIGHTLY faster processor. I was unimpressed with the PSP Slim. Take the old PSP instead.
I haven't had a chance to try online gaming with it but from what my friends told me, it's awesome.
Sony really needs to get off its duff and crank out more games for it. A friend at work sold his because he was sick of waiting for Resident Evil or Silent Hill to be released. I guess I have more patience than him.
