ill be honest , i do see a difference between the two ... obviously the screen , but it really doesnt impress I much . i love my `` fat '' ds ... and ill stick with it . all i know be that nintendo will be laugh there butt off because be get sucker into buy there so call `` vastly '' improve product . I mean , they have do this to we for as long as they start the portable line ... gameboy , gameboy pocket , to gameboy color , and to the advance . now i will say that the sp upgrade be necessary , because we all need a real backlight-not those cheap wormlight they be offer we . but now they even have a BETTER sp . . with the improve backlight . another one for the sucker , eh ? when i purchase the d , i knew they be come out with a new model-even for people who didnt , they could make a really good prediction , right ? people be go to buy this for 130 buck and no more than a year and a half later , they will have a new system-and people be really go to want to beat there head with a board for do that one ... im not try to di the d lite completely , but smart people will hold on to basically the same portable until the NEW portable to come out - dont let nintendo sucker you guy , just keep with the good old fashion model and save 130 buck , eh ? if you disagree with I or even agree , please comment I with my email . its juggalo1_9_9_2@yahoo.com later
