Just checked out the Panasonic web site. First thing that struck me were
the prices! $510 for the top cordless drill model (15.6V Multi Drill &
Driver with 1/2" Keyless Chuck). As you say, all nice and compact. But the
high price made me think that Panasonic tools must be an elite brand. Then
checked out prices for these very same Panasonic models at several online
retail tool vendor sites, where I found the prices to be much more in line
with the competition. For example only $299 (virtually half the price) for
the above model at Tool Authority
(http://www.toolauthority.com/manufacturers.php?MID=21). One observation
though, in general the Panasonic cordless driver lineup seems to offer
somewhat less torque than competition such as Hitachi or Bosch drivers, even
in models where the voltages are the same. But I guess the extra compact
design of the Panasonic drivers I guess could very well account for this.
BTW, another question I have just came to mind: what is the
significance of "Ah" (e.g. 2.0 Ah, 2.5 Ah, 3.0 Ah, 3.5 Ah, and so on)
rating of a cordless tool's battery-capacity? Up til now I had just assumed
this referred to amperage-per-hour output (which, like the amperage rating
of a corded tool, if multiplied by the voltage [e.g 12. for 12v. cordless
models, between 110 and 120 for all corded models] yields maximum energy
output [or consumption, respectively] per hour). But I'd like to somehow
find out for certain from someone if I am on the right track in this or
not... Because if this is true how can the most powerful cordless tool
possibly keep pace with an average corded one which has far higher, both,
amp and voltage numbers? Thanks.

The AH rating is how much power is available. Some tools use that power
more efficiently than others.
None can truly keep up with a corded tool long term. They may have equal
power for a short time, but there are compromises to get decent run time
from the batteries.

Going to be interesting to see how the new Milwaukee V28 Ion line holds up.

I love the Pit Stop and Helicopter commercials. Check their web page if you
haven't seen them.

Hadn't seen the helipcopter commercial before. Thanks for the link. :-)
