I don't really use portable games anymore. I used to, but I sold my DS a few months (or years, I don't really remember when it was) ago, and haven't looked back since. If I'm bored while out of the house, I usually reach for [insert gasp here] a book, but I've been known to borrow an iPhone if it's readily available for a few games of whatever they have installed... which usually amounts to Solitaire.
When I did use handhelds, though, I was Nintendo all the way. The PSP did a lot of things well, but the GameBoy and DS just had more to them in my opinion.
