I have the good old PSP 1000. My friend has a Nintendo DS. I will play both BBS and 358/2 Days for sure. I will buy BBS. However, for my birthday coming up later, should I get myself a DS to be able to have my own 358/2 Days? Or should I upgrade to the PSP-3000(or 4000 if it'll come by the time BBS comes to NA) so that I can enjoy BBS with richer colors and slimmer PSP? I could borrow my friend's DS after he is done with 358/2 Days. The thing is that if i get a DS, it would just sit there and collect dust when I'm done playing 358/2 Days, as it is the only DS game I want to play.
