Ok so I had some gift cards from Best Buy so I went to get a 16GB micro for my Dinc. I went to the cell phone department and they only had one left - it was on sale for $69.99. Works fine but was later looking on Amazon and saw what I thought was the same exact card for like $29. Hmmm... but then I looked further down in a search and saw that the SanDisk "mobile" microSD card was $78. I looked at the packaging for the card I bought at Best Buy and it also says "mobile." I'm assuming they make different micro cards.. one for mobile phones and one for other electronic devices? Are they shaped differently? Do you absolutely have to use a "mobile" micro card for a cell phone? My other question is - when I put my new micro card into my card reader, it fit a little more snuggly then I would prefer. The 2GB card that came with my Dinc did not fit so snuggly. Is there a difference in width? Should I get a new card reader? I've had my current one for a couple years. Many thanks in advance!!
