Now, check what class your card is (it's that little circled number). Is it a 2 or 4? For best performance, you really should be running a faster (and thus higher class) card for apps-to-SD.
A lot of us scoff at throwing out $50+ for a Class 10 card, but guess what. Newegg is selling a 16GB Patriot (yes, not some generic Chinese brand from eBay) LX Series Class 10 microSDHC card for $19.99 with free shipping. And when you complete a mail-in rebate (thorough instructions here), you get a $10 credit good for anything at Newegg.com, bringing the final price down to an incredible $9.99.
I haven't quite decided if I will be grabbing one for myself, but this is definitely a steal when it comes to removable media. The deal appears to be going until February 1, so you've only got a couple of days left to make up your mind.[Newegg]
