Look, the PlayStation Vita is still a ways off and the PSP has a pretty huge library.
So you may as well take advantage of a new hardware bundle Sony will offer at the end of the month. As revealed at the PlayStation Blog , Sony will introduce a "two-fer" PSP entertainment pack: it drops on August 30 and it includes a black PSP-3000, 2GB Memory stick PRO Duo, and both Madden NFL 12 and Need for Speed SHIFT on UMD. You can grab it all for only $159.99, and the fact that it includes two top-quality games should be more than enough incentive. Let's not forget that the PSP launched with a $250 price tag…now, with a ton of available titles, you can get it for $90 less plus two free titles. Look at it that way.
Personally, I don't even play handhelds much, but I'm glad I have my PSP. Being an old-school RPG fan, I actually have some options. Besides, it's gaming on the go; nothin' wrong with that.
