Flash drive

I don't know much about computers, I don't think I ever will. I just know the basic stuff and that's all that matters. I can email, I can facebook, surf the net and blog....what more can I ask for? Seriously, I sometimes wish I'm a bit more techy. That'll save me a lot of money paying "professionals" to do simple pc repairs or upgrade. And it'll be nice to know what the difference is between a regular and Branded flash drive. Other than the price, is there really a big difference???
