Both the PSP and Nintendo DS are good systems to pass the time playing games with, although which one is better can only be judged by the preferences of the person playing with them. If you prefer an upgraded gameboy system with added pen support then go for the Nintendo DS, although do not expect any ground breaking graphics or sound from the system, this on the other may be what it may appeal you and that is simplicity, in fact thats why many small kids still play with a gameboy these days. The psp on the other hand is a relatively new breed of machine which earns the respect of being much more powerful, the games will get better for sure as they will definitely use the power better in the future. If you like the sony playstation consoles, the psp is a better choice. It really depends on your particular likes and dislikes. Anyone who says that any of the portable consoles will disappear is very much in my opinion stupid…and anyone which starts talking about sales and other stuff misunderstood the whole argument…
