Now i have the opportunity to either get a PSP or and IPOD TOUCH and I am finding it difficult to come up with a decision. I only need a device which can watch movies in HD, play games, listen to music and browse the web. My only problem is that I do not know how exactly big and wide the screen is( I'm REALLY FOCUSED ON THIS PART ). This is because I plan on watching a lot of movies and do not want to make the wrong choice. PLEASE HELP
