Although iPad is great for playing games but still it cannot match standalone game console such as PSP and Nintendo DS. First reason is the game variety. PSP and Nintendo DS have been around from a long time and therefore have bigger library of games.
This means they have a game for every occasion and interest. Another reason is the controls. Standalone game consoles have more intuitive controls than iPad, which is more or less dependent on touch gaming.
IPad does have the advantage of bigger and brighter screen but at the very same, its dimensions effect its portability. PSP and Nintedo DS are certainly easier to carry around. The last important factor is pricing.
Both the game consoles are considerably cheaper than iPad and hence are more pocket friendly.
