Question here is: Why I bought this PSP GO? (why a handheld?) answer: My work travel is about 45min long (train) if there isn't any delays. My fridays trip was 1h 30min! It's a long time. Yes I did listen music and watched some videos on my Ipod but I was thinking again "I could be playing games at this moment" So again I started to think should I buy handheld gaming device? I searched littlebit and I checked Ipod, psp and Nintendo DS gaming offers. price was of course big thing and quality of the games. It was also important that device could with easily to my pocket. DS is pretty expensive (about 170-200e) without games. good games even if I would buy them somewhere else than Finland would cost me about 30-60e. Then I found about this great offer about PSP GO. 179e and 10 games (free). With PSP GO I don't have to worry about UMD Discs or anything else. Everything would be on the flash memory. so.... I'm getting PSP GO upcoming week :) I will tell you my thoughts when I receive it :)
