Not true. The Nokia N800 and the new N810 do, along with several digital cameras. Even the cheapie multi-card reader I bought several months ago supports SDHC The SDHC spec has been around long enough that Sony could have incorporated it into the 550. I think it was rather dumb of Sony to release a new reader without SDHC support. The only reason I can think of for doing this is that having SDHC would have greatly lessened the use for a Memory Stick, which Sony owns the patents on. I'd rather have something like SD, SDHC or CF, which is more widely supported.
