I read about a few of y'all using the bulk Sandisk SD cards in the Focus. I'm wanting to go a bit more higher end and from the same manufacturer as the phone. This is the card I'm looking at http://www.amazon.com/gp/aw/d/B005TUQV0E/ref=mp_bxgy_p_dp_y?qid=1335912129&sr=8-1. Is there any reason that I shouldn't go for it other than the price?
Don't bother. You'll never be able to use that card in another device again (unless you have some hard-to-find Nokia N* device). Save your money and apply it to a new WP8 phone somewhere down the line.
I know I'm super late in replying, hopefully it isn't too late.
