256MB microSD™ Card, World’s smallest memory card

As more and more advanced, and compact mobile devices make their way onto our shelves, the demand for smaller, higher capacity and better performing Flash Memory Cards increases. The multimedia applications that many of the current Smart Phones, PDAs and Pocket PCs, are memory intensive and require the extra memory capacity of a memory card for storing photos, music and data. With this in mind and to ensure you get the most from your hi-tech devices, Transcend Information Inc., a world leader in flash memory devices, has developed its latest high performance 256MB microSD™ Memory Card, and at only half the size of a mobile phone SIM card it is the smallest memory card in the world.
The microSD™ card’s really tiny size and impressively fast data transfer speeds of up to 10MB/sec make it the perfect choice of Memory Card for use in the next generation of mobile phones, which include a memory card slot as standard. Transcend’s microSD™ card can also be used in regular SD™ memory card slots by combining the card with its provided adapter, thus ensuring that the microSD™ card can be used in all compliant SD™ card devices.
Now you have the convenience of being able to save your photos, MP3 music, or MPEG 4 video clips onto one tiny 256MB microSD™ card, which can be used in your personal mobile devices.

The only problem encountered based on consumer reviews i've read is that when using the mini SD was when using the adapter and trying to increase the storage of their flash based MP3 player. For some reason Windows Media Player said that the disk was invalid. So they're not sure if that was a WMP. Some wished they offered a larger memory capacity than this for the Mini SD.
