Summary: The fact that this baby holds 8GB is just amazing. I'm not really sure why I bought it considering I'll never actually need 8GB worth of memory if I'm just shooting JPEGs on my digital camera, but there's something about having this much memory that makes me smile. The part that doesn't make me smile, though, is the fact that it's still Sony's proprietary format. I can't swap this with any of my other non-Sony devices, and if I buy a new non-Sony camera, this memory stick (which will have likely depreciated greatly in value) becomes useless.

Summary: This is a phenominal product. Sony continues to maximize space capabilities while maintaining its sleek design.
This memory stick enables you to capture thousands of high-res images without having to constantly download to clear.

Summary: I bought this card to use with my PSP, and I'm quite glad I went with the Sony Memory Stick PRO Duo. Since I plan on using the console as a MP3 player as well as a gaming device, the 8GB provides me with adequate space to not only hold my music, but also my game saves and any other media I need. The PRO Duo also has a fast file transfer speed when used with my MacBook Pro, which is another plus. I'm pretty sure that 8GB is the largest memory card that's on the market at the moment, so I definitely recommend this one for anyone who's looking for lots of storage space for a reasonable price.
