What is Acer Liquid Metal maximum SD card speed class? I want to buy a new sd and I'd like to get best bang (and speed) for the buck...
But I can't find this information...
Anybody knows?
There's no reason a class 10 card wouldn't work.  The card being faster shouldn't break anything.  I can find no evidence that the Acer Liquid Metal detects and behaves badly with a fast card, or does not use the SD card specifications properly, or anything like that.
