I see lots of posts but nothing definitive.
I intend on using the 1080 video recording on this device and I store lots of images to show clients.
Do we really need a Class 10 or is 4 sufficient for these uses?
From what I've read, class 10 shows no improvement in cellphones due to other bottlenecks, than class 4 or 6. Where they really shine is in DSLR cameras. Class 4 or 6 is sufficient where anything else would be a waste of money.
