I was looking at the price of M2 memory, and it's dirt cheap. You can get 16GB for only $20. You can get an M2 to Pro Duo adapter for likely around $5 after shipping. I know adapters are always an iffy endeavor, but has anybody successfully gone this route? I would love to double my memory for cheap, and this would be a great route to go. Plus, then I could use my 4GB MicroSD cards elsewhere. I know, I know, I can get an 8GB Pro Duo card for about $20 too, but if I can get double the memory that is still fairly reliable (I'm thinking official Sandisk adapter), that would be great. Edit: I don't need a speech about the best types of memory either. I'm fully aware of what is considered the most reliable investment, but I'm looking to get the most bang for my buck.
