Have mobile phones become more important than our wallets? If they haven’t, they’re certainly moving in that direction, and the Case-Mate Google Nexus One ID Credit Card Case serves to remind us of that point. Why use cash when you can use a credit card, right? This case allows you to slip in two credit card sized items of your choice, so you can probably just get your ID and credit card and run away from home with your beloved Nexus One. If this is the case for you, you’ll need to shell out $29.99 to get acquainted with it.
