I'm happy with my T410; I ameliorate the ergonomics
by using a wireless USB mouse, and a compact
USB keyboard.
I disabled the touch pad, otherwise I
get spurious mouse clicks.
I use a really cheap Acer Extensa 5220, keyboard is ok for me, it has a
rather conventional layout compared to some laptops I've seen where
ESC/Shift/Enter/... where all over the place. The touchpad works ok for
me, although I started to use a mouse again when at home. Touchpad is ok
for the occasional pointing, but if you do point-heavy stuff it can go
so far that your fingertips heat up and you almost start to rub them
off.
I think that's where the fingertip-rolling technique comes in.
Fingertip-rolling only works for very small distances for me, so it
doesn't really help a lot.
You move around a lot more and faster than I do on a touchpad!
The touchpad can be disabled using Fn+F7 but this happens pretty
much in hardware as far as I know and can lead to xruns (same goes for
backlight).
Toshibas have a function key combo that disables touchpad. I've never
noticed if it has any impact on xruns, cuz I usually use external
keyboard and trackball except on mobile recording trips (like recording
my church band this morning) - then I need the touchpad.
Can't imagine why backlighting would have any impact on xruns. I'd
figure that would be subsumed in the general impact of laptops' power
management hardware on things like processor or bus speeds.
I assume it has to do with hw-interrupts or somesuch. I'm talking about
manually changing the backlight level using the key combination, I use
little automatic power management features and nothing that changes
backlight automatically because to me that's just annoying.
I don't think I've ever manually changed the backlight level on any of
my various laptops. My wife's netbook automatically dims. I found that
annoying initially, but it brightens back up when you do something with
it, so it's really minor.
Possible that those Fn+key combinations are activated by the laptop's
ACPI BIOS (or equivalent). I doubt many BIOSes are RT safe!
