I know that Edge is "supposed" to work up to 32gb, but has anyone actually tested it at 16gb? I want to upgrade from my 2gb. It's just not cutting it anymore for me and I want to know what works. Most topics are talking 4 and maybe 8gb, so maybe it's time for a new one. Sorry if this is old. What do you all recommend out there? (ie. Brand, size, class) Thanks.
