Almost 1 month since I switched to an Aspire basic setup (BVC and CF battery) and I'm 101% satisfied.
Even though I've read many users complaing about leaks and burns of the BVC system, mine works perfectly, and I'm looking forward to get my nautilus asap. 8-)
Merry Christmas!
Actually, a decent idea just came to mind from reading that you lose yours often (I do too!) ... how about a battery with a lanyard attachment? They aren't very heavy, I don't think it would fatigue anyones necks.
