Sorry, not true. Their full size 4GB SD cards include: TS4GSDHC6 - HC Class 6 - requires kernel support TS4GSDHC - HC Class 2 - requires kernel support TS4GSD150 - Legacy 150X TS4GSD80 - Legacy 80X TS4GSDC - Legacy, unspecified (lowest) speed I'm using the term "Legacy" rather than "Standard" for non-HC cards, since 4GB is outside the original SD specs and presumably varies by manufacturer. I have two TS4GSD150 cards arriving Wednesday 1/17. Will report back.
