The OCZ Secure Digital Trifecta 1GB isn't the fastest microSD-card out there, but what it lacks in speed it makes up for in ease of use. Because it comes with the SD / USB adapter it's easy to transfer data to and from it using a variety of interfaces. This card can be used in a large number of different digital cameras and mobile phones. It makes sharing data between all of your gadgets a breeze, because you don't have to have a PC with you.
The only real downside to this card is the performance since it's only 66x which means that this card is struggling a bit when you hook it up with say a 10MP camera. You can feel the difference of almost 5 MB/s write speed because the camera spends a second longer writing a picture to the card. Unfortunately the microSD form factor is still difficult for all manufacturers, so microSD devices are always slower than regular SD Cards.
Overall I like the card a lot because it's so versatile, it's the perfect card for some one who has the need to share information between a PDA, mobile phone, and camera.
