Considering these kind of graphics were on the PS2 when it first came out no. The graphics are great for a portable gameplayer. But we all know graphics come second to gameplay and getting the right games developed for your machine, right? Millions of people have downloaded emulators so they could play Super Mario Bros all over again, it's all about fun- not realism.
Portable game-playing does a lot more than you guys give it credit for. Look at Pokemon, I don't like it myself but a HELL of a lot of people do and it's been one of the most successful game-series of all time. All through a GameBoy.
