Big new technological advancements ?

But of course nothing will be cheaper than building your own rig.

That keeps swinging back and forth. There was a time where it was MUCH cheaper to build your own....then for a while it was not, and now it definitely is if you want specific features, but is not if you want some fairly basic stuff. It's a hard one to keep track of.

Speaking of batteries... which is what I thought of before I entered this thread... things look bright if this works out: http://phys.org/news/2012-05-nanostr...batteries.html... nothing like a ten fold increase in Li-po battery capacity

Doggone batteries are kind of like fusion: We are a few years out...and always will be.
