Alright, alright already... Yes. I agree. Curiosity kills the cat. Consider me a cat with a deathwish!
I couldn't help myself and have installed eboostr on my aging first generation centrino notebook (1.4Ghz, 2GB DDR PC2100 RAM, 120GB 5400 rpm harddrive) and am giving it a go. I set up three different caches on three different USB devices - two thumbdrives (394MB and 987MB respectively) and on my new USB 3.5" HD (4GB cache). So far I am not sure if I am experiencing the placebo effect or not... Certainly boot times are not affected as far as I can tell (though I *think* my desktop icons paint a wee bit qucker, but I need more observations) but general operation does *seem* brisker. Currently, I am runnig Word (all Office apps are 2003 Sp-3) with 5 documents open, Excel with 1 spreadsheet open, Endnote X, Maxthon 2.06 with 12 tabs open, Dopus 9.1 with two panes showing, no preveiws and no additional tabs loaded, Outlook and Powerpoint with three presentation open, one of which is 17MB (haven't optimized the graphics yet). I should stress that I was able to do this with minimal drama WITHOUT eboostr installed and set up, but I am certain that my machine bogged down a bit more than it is at the moment.
It's early days yet, but I think I'll give this a couple of days. I AM concerned about wear on my thumbdrives and on the external HD, though... Will report back when I have more to tell you all.
