Advantages: Large memory, easy to insert
Disadvantages: Can't copy data

...Whith a small size and a large memory, this memory stick is good for storing music, videos, games and even the odd movie or two. This format of memory stick is for gizmos and gadgets like most sony ericson phones and psp's. The MagicGate standard for Memory Sticks is an encryption system allowing music to be downloaded to the card and played back by an authorized device, but not shared. Certain standard Memory Stick and all PRO sticks are MagicGate compatible. The Memory Stick Duo is slightly smaller than the competing Secure Digital format and roughly two thirds the length of the standard form factor. It was developed in response to Sony's need for a smaller flash memory card for pocket-sized digital cameras and cell phones. Memory Stick Duos are available in all the same variants as their larger cousins: normal ones limited to 128... Read review

Advantages: Memory, Memory and more...
Disadvantages: Small and you don't get a sleave to store them in!!!

...This is a little Gem, although some may say that on a weight for weight basis Gold would be cheaper! Sony have always had their hand in bringing us high quality electronic products, who can argue that their TV's are second to none, certainly not me! And they have expanded upon that with venturing into other fields of electronics bringing with them their expertise... This brings me to tell you about this product which in itself is a tiny part of Sony's empire. When i say tiny i mean tiny, one needs to be careful as not to lose it. I myself have taken great care in keeping my 4 Pro Duo Memory Stick's quite safe As i said i have 4 of these, two are 2Gb, one is a 512Mb and a 64Mb. All of them are Sony! They are invaluable to me as i have a PSP and Sony Erriccson K750i which they can interchange with as and when i please. They will fit... Read review

Advantages: Cheap, Convenient and Reliable
Disadvantages: Memory Card Sticks Out - Some Little Annoyances

...The “Sandisk MobileMate 4-in-1” provides an alternative way of storing data than the typical flash USB drive/external hard drive plus makes the most out of one’s memory stick/pro/pro duo. Being a student I needed something to transport work to and from school and, with the technological advances and the amount of work I had to produce it would have been absurd (and frankly taboo in school life) to walk in with a floppy disk! Using CDs would be impractical and limiting to the school facilities thus I needed something fast, convenient, reliable and cheap (being a student and all)! Cue in the “Sandisk MobileMate 4-in-1” In terms of convenience it was perfect for me considering the fact that I had a Sony 2GB memory stick pro duo from owning a Playstation Portable (PSP). Moreover combining Sony’s record of reliability (from my experience... Read review

Advantages: Compatibility, Very Small, Nice Looking
Disadvantages: Price

...I purchased the Sony 512MB Memory Stick Pro Duo for my new Sony Cybershot DSC-W50. It works great! I can get over 150 pictures at 6 mega-pixels and up to 23 minutes of captured video. The price is unbeatable too! I've had a
