Class 4 or Class 6 does it make a difference for a tablet pc? I bought a new tablet PC and am planning to buy a new 32 GB Micro SD card for it. I looked two cards of same memory. One is a class 4 card and other a class 6 card. with a price difference of 10 dollars. Is going for a class 6 card really needed? Few specs of this tablet PC - 0.3 front cam, no primary cam, plays HD videos, 4 GB internal memory, 512 MB Ram & 1.2 GHZ processor. Android 4.0 ICS, let me know if purchasing a class 6 card really makes any difference in tablet performance. Thank you in advance Anoop.
