Well watching it on the 55 inch TV in the living room makes me go cross eyed. . Cinema opening soon. Box of paint - entry fee.. Popcorn.. BYO .DS can also be used to browse the 'Net... Dual screen porn...yay!
I have both, as I travel a lot. I like the DS better to be honest.
Oh, and anyone that watches a film on a screen as small as those on a DS or a PSP is a complete and utter tw@t.
