I as well. Tom-Toms do work and tend to be less expensive for similar
features sets, but they don't seem as polished in minor but annoying
ways. For example, one of the earlier ones I borrowed for a weekend was
insanely road-locked. It always showed you on the nearest road if there
was one within about a half-mile of your computed position. Would that
have mattered in any practical sense for a car GPS? No, not really. But
it still bugged me that the pointer would stick at the edge of Main St
as I drove into the parking lot, then suddenly zoom over to the edge of
1st Ave as I got closer to that than Main. Garmin have their quirks and
annoyances as well, but it feels like they're fewer and there was
usually an ATTEMPT to mitigate it in the software, even if it wasn't as
much or more than I would have liked.

But more directly addressing the question: It's hard to find a current
GPS that doesn't support WAAS, and manage it pretty harmlessly.

Generally for any of the current units, you're not going to get a huge
number of pixels no matter what.

Again, back to the actual question, a couple of hours is typical. Might
be two hours, might be four hours, but it's not going to be much more
than that for an automotive-oriented GPS. And if respectable screen size
is important, you're not going to want one of the longer-lifed hiker or
multi-use units.

It's probably LESS important if you're still finding your feet with GPS
use. Buying a new unit will always come with a newer map/POI set, and if
after owning a GPS for a while you end up with a much clearer
understanding of what features you use and what you don't, what appeals
and what annoys, and the background of use to research the next purchase
much better than this one, you may only keep a first GPS for a year or
two before buying a "keeper". Under that circumstance, lifetime maps on
the "starter GPS" may be unimportant since they won't really have time
to get stale.

Some units will also integrate an FM transmitter into the power rig,
similar to the aux input. That can be useful for people that (for
example) use several vehicles commonly, or rent cars a lot.
