Honestly, I am very impressed with the graphics in Black, now that I have a DS and Black. I look forward to playing Diamond and SoulSilver but I'm glad to see that the graphics have dramatically improved.
I know what you mean, that's why I have a MacBook Pro and not a MacBook Air... That and the larger hard drive space. But yeah, the lite will work for now.
But yeah, I do intend on trying B/W2, simply because I hear that the game is set two years after Black/White - I would like to see if there are any significant plot differences... And of course, I hope that it is significant and good - unlike the G/S/C treatment of Kanto.
The DS Lite is awesome and so comfortable, but I can't help but be attracted by that bigger screen on the 3DS XL, as waste of money as it is to buy a new DS just for that since my Lite's working totally fine. XD;;
