Here's a tip- keep it rigged up and ready to go in your gig bag.I keep mine in an Acoustic Image head bag that Rick schwagged me at a conference- adaptor/extension cord/tripod/usb cable... When you get the mojo to create, you're ready to capture it. I use it to retain composition ideas. Once you get used to having it around, you'll use it a lot.
'Nother option is a cheap roto-mold pistol case, (DoskoSport for instance)... You can usually find 'em at sporting goods stores for less than $10... My son did cutouts into the foam on his, but mine sits snuggly without the cutouts, (or the hassle!) Also, since the foam pulls out in one piece, I can store the manual in the case out of the way...
I play with a singer/songwriter who has an H2 but never uses it. He has dropped more song ideas, which is infuriating! There's really no reason to... Just set the thing up on a stand and record everything you do... Whenever we get together, I pull out my Zoom at the start of the session and record until we are done... No need to hassle starting and stopping the unit, and since fidelity isn't too much of a concern for idea grabbing, I can record at a lower resolution giving increased time... More than once, I have proven to him the utility of the unit, but still nothing when he's alone... (I only bring this up because I heard it all again at rehearsal on Friday!)
Another tip, when doing songwriting/idea capture sessions, the recording time can get kind of long. It can be a hassle when editing in Audacity to find your latest 'brilliant' idea... If you take a pencil and tap the mic grill immediately after your masterpiece, the peak shows up easily in the display and helps you locate it quickly!
For loud shows with the band, I set the mic preamp to low, level at 100, mode to 44.1 / 24 WAV and go... Putting the unit toward the back of the room captures easily without distortion and lets me prove that, yes, that was the guitarist off key right there! Validation!!
