Anyone using an iStomp?

I just read a review of the DigiTech iStomp in the latest MF catalog and I'm not sure I really get the usefulness of such a pedal. I'm a software engineer so the concept appeals to the computer geek in me but, in practice, is the iStomp useful? if I want multiple effects at my disposal simultaneously I'm going to need multiple iStomps at $140 each. At that point I may as well buy separate boxes from whichever manufacturer makes the effect I like the most. I understand that the iStomp might make financial sense if I only need, say a chorus and delay for one gig, and a distortion and flanger for another, which means I only need two iStomps and have access to four effects. But if you need many effects at a given time, it seems like separate boxes or something like a Pod makes more sense. Or am I completely missing something?

I've never spent $140 for any pedal, and the fact that I can reprogram it seems more geeky than practical. No thanks, call me when they're ~$70 each.
