Has anyone tried Eboostr to improve performance?

Here's my opinion of REadyboost (The eBooster is just readyboost from Vista for XP)...

I work for a mid sized company and have a lot of resources at my disposal... I've plugged 15 different flash devices/memory devices/removable drives/etc into my Vista machine, and each one asks me to improve my windows performance, I tell it to do it, and each one then tells me that the device doesn't meet the standard to improve my performance. Each of these flash devices is from a different manufacturer ranging from 1gb to 4gb and all are USB2.0 on USB2.0 compliant hardware...

So... I've not found a thumb drive that works for this yet, and I've got a fair bit of resources available...

I had some initial problems with getting this to work, but i was using kind of older usb memory sticks, went out and got 1 that was certified for vista boost and it worked no problem, i have not noticed much of a performance boost though.
