So right before my daughter was born (like 2 days before) a month ago, I went out and picked up a PSP. I got it because I, as a PS3 gamer, was interested in the interactivity between the two. so I headed out to Best Buy, and picked up the Silver Daxter Entertainment Pack for $200. It came with the silver colored PSP, a 1GB Memory Stick PRO Duo, a copy of the game Daxter, and a copy of the Family Guy Freakin' Sweet Collection, both in cheap cardboard sleeves. I figured for $30 more than the black PSP with nothing else, this was a better deal. Plus, the silver is a nice touch.
So after having it for a month, inheriting some games from my brother-in-law Marc (one good, one not so good, but my son likes it), and buying one more game for it (GTA: Vice City Stories), I have to say that I am very impressed with it. I know everyone may think I'm just a Sony Fan Boy, but that's not the case. The PSP has all the media functionality of the PS3, just in handheld form.
I was, however disappointed with a few things. The interactivity between it and my PS3 work great while I'm at home with a direct ad hoc connection between the two, but when I'm away trying to connect over an internet connection, I can't log in to the PS3. Maybe I'm doing something wrong, but every attempt has failed thus far. Another gripe is that, since my Powerbook G4 died, I've been using my ASUS Eee PC exclusively, which runs Linux, and it does not support the PSP when I connect it. Now that's now really a PSP problem, but more of a Linux problem (or the Xandros version of Linux).
All in all, I'm very happy with my PSP purchase. and Daxter is a pretty awesome game, too.
