Can someone please tell me whether the class of microSD really makes a difference for practical use? I don't care about transfer time as much as playing videos, music, etc. without lag (if the class can even affect this). It seems as though for a 16GB microSD, each class costs $20 more than the next class down, and I really don't know that I want to drop $60+ on a microSD (the cheapest I see a 16GB class 6 on newegg) card unless I must. Also, if anyone knows of a good deal on a Class 6 16GB, please do share! Thanks EDIT: My bad, this belongs in Accessories if a mod cares to move it.
