[quote name='UltraMysteryDopplega']The PSP is a much, much better system than the DS (I have both), but I would not under any circumstances get the Go. Over the DS, the PSP gives you a much bigger and nicer screen, better controls, and a much more powerful system. PSP games are roughly like PS2 games at a lowered resolution and generally a lowered framerate. DS games are a lot more similar to PSX/N64 games. The reason to avoid the Go is that you don't want to lose UMD and be stuck buying games on the marketplace, and the older PSPs have easy to install emulators for pretty much every system and a perfect CPS2 emulator that lets you play greats like Aliens vs Predator (arcade).[/QUOTE]
Agreed 100%. I have several PSP systems, including the original "Phat" model, a few 2000s, and two 3000s. The PSP blows away the DS in terms of hardware; bigger screen, better resolution, more powerful CPU and graphics processors, better front panel controls, nicer form factor. The DS is just totally underpowered, low-res, awkward to hold, and 99% of the games are shovelware and kids games. And the silly 2nd screen is a gimmick, useless in almost every game released for the system. They should have focused on a single, larger, higher-resolution screen, instead of the gimmick of having 2 screens, when designing the system.
As for the PSPGo, I like the design of the hardware, but the digital games are a ripoff vs. UMDs. I much prefer to have games on physical media for any system anyway. When the PSPGo drops to under $100 for a new system, I'll consider getting one; but even at $150 new/$100 used, it isn't worth it, IMO.
