Hmm, someone asked for a good game? Get Untold Legends; it's constantly reffered to as the 'Diablo II' of PSP, and even though that definition is a little off, it's still a great game. Turn on the WLAN switch and play multiplayer with up to four players, and you can build teams with specific attributes with your friends.
Get Wipeout Pure for web browsing on the go, and you're pretty set for a while. As for myself, I'm just hoping for an update for the web browsing rather than buying the game, but it's really whatever floats your boat. A neighbor of mine has a wireless internet connection in his home(which I've been leeching off for a while), and surprisingly, I can get a 20% signal strength around 1/2 a mile from his house! O.O
Truthfully, I'd reccomend a good quality memory card rather than a second game though. If you get PSPVideo9(just make a search), it makes transferring movies to a memory card fairly simple, and by tweaking the settings a bit, you can fit two or three decent quality movies on a memory card with enough music for some songs. In my opinion, the $95 you'll pay on a 512MB memory stick pro duo is worth way more than two extra games for PSP.
If you wait until the 2GB memory stick is widely distributed around the USA, the prices for the 512MB and 1GB memory sticks will probably drop dramatically, so you might want to wait it out for now though.
I have no trouble seeing PSP replacing iPods and other gaming handhelds in the near future. Incase you don't know, the PSP's performance is even higher than what we see now. It's a widely known fact amoung PSP fan people(well, not really)that even though they've listed their CPU speed at 333Mhz, it's been underclocked to 222Mhz. Why? Probably battery life, which means when Sony releases a higher quality battery pack(which they have stated to be working on), we might see the full potential of the PSP unleashed in the near future.
With PSP on the market now, it has been a struggle for retailers to sell their NDSs, and in the near future, when PSP at it's prime, I have no idea what retailers will do about the DS. And that isn't even a rant; thats a fact. Even while PSP hasn't been able to reach it's demand, it's still outselling DS weekly. Bluntly, that means for the majority of the population, when a PSP isn't in the store to sell, they won't settle for a DS in the meantime, no matter how many of their systems are in. How much furthermore after PSP gets it's little upgrade? They could make a UMD or use it's wireless connection to make this large update, so it's a very large possibility. EBgames is giving away promotions already for DS trade-ins, and offers like $30 off a DS when you buy it with a game.
Sony really should have made a larger-capacity battery pack though. It seemed kinda risky for them to enter the market with such a low level of quality on such an important feature. Whatever.
Oh yeah, Darklink. That's not a browsing 'glitch' really...
