I am looking to purchse a samsung galaxy mp3 player, i was curious if it had the capability of hold a 64 gb sd card or anything larger than that, if they make them. I have a Asus Transformer pad tf700 with a keyboard. I am looking to purchase a 128gb sd card also to hold my music and documents on. I am looking to substitute my laptop with my Asus tablet. I was hoping i could transfer music from the tablet onto the mp3 player. If so can the Samsung Galaxy mp3 player read a 64 gb sd card? I am also looking into a zune i was also curious if my Asus Transformer Tablet has the ability to transfer music to the Zune? Please help me out.
