BlackBerry-obsessed individuals, pay attention. Plia Designs has created some fashionable PDA Universal Cases that are perfect for those times when you don't want to carry a big purse. There are many chic designs to choose from and each case offers a hardshell exterior with a purple velvet interior. They are even big enough to put some cash, your iPod or business cards inside of as well. Now for the unfortunate part, they cost $72. But if you think of it as a mini cute purse and a way to protect your $150-$300 BlackBerry, it could be justifiable.
