Hm, 've been thinking a bit about this, and I won't go for the upgrade.
<a bit of a rant>
I just like the way USBSR works, disconnecting my USB drives easily and safely, and I don't need nor want the extra features of Zentimo. It kept nagging me about a speedtest for every USB drive I sticked in my system, but what is it good for? I bought it, so if the speed wasn't good enough (compared to what? my other USB drives?), I'm stuck with it already

And getting at the 'unload drive' option takes clicking on rather a tiny button, and the extra's I never need are hidden behind even more tiny buttons.

But last years give-away, non-upgradeable, version does work fine over here
