Using 4GB on an fast 8GB sdhc card and it makes my Aspire One ao150 downright zippy. Foe example pre eBoostr Word 2007 takes 7secs to load first time after startup and 4 secs subsequent starts. With eBoostr it stats in less than 2secs all the time.

While the difference is not a significant amount of time the difference it makes in the feel of the computer is incredible.

So far not even a int of a bug and I have been using it for 4 days.
