I'd looooove to get my hands on a Festool 120v DR-18/4 drill, for the simple fact that in very cold weather cordless tools just lose their oomph.
How cold are you talking about here? I thought cold temperature performance was one of the advantages of Lithium battery chemestry.
I've found that Lithium Ion batteries tend to suffer a reduction in performance in temperatures cooler than ~10 F/ -12 C. This becomes particularly pronounced in temperatures below 0 F/-17 C. Also, the batteries frequently won't take a charge at those temperatures either, requiring you to warm them up before the battery will be accepted by the charger. I've experienced this phenomenon with my Festool, Hilti and Makita Li-Ion batteries.
Granted, I REALLY prefer to not be working in temperatures below ~ 15 F/-9C, but sometimes circumstances trump my comfort and I need to get some work done. When this happens, I need to know that my tools will work and not be a liability.
Years ago I flirted with going largely cordless. Recently, the pendulum has swung to nearly the other extreme for me, where now if I have the option, I generally prefer to go corded. I don't need to worry about losing batteries, jockeying charged and discharged batteries, etc...
Of greatest importance, I don't feel locked in to a battery platform. If I feel that a certain manufacturer has produced a particularly well engineered tool, I just buy it, rather than trying to fit within a battery platform that may or may not reflect the full scope of my wants and needs. For instance, right now I'm rockin' a C15 for my drill and a Makita LXT digital impact driver...
