I've been using my R51 for five years or so (and this message
is sent from it), and it has never failed to do what I wanted.
This one is from the IBM years, and it's certainly solid and
dependable. The only thing that has degraded so far is the
battery, down to more or less half its original capacity.
I don't know if Lenovo is up to the same standards. Never
used the modem, but all the rest has worked nicely. Also
never used any 3D-graphics drivers.
As for audio I've mainly used it with USB cards, either for
recording or mixing, always with -n 3 -p 256 and that worked
very well. I've used it to mix 24-track Ardour sessions.

Of course chipsets etc. change faster than you can imagine
and current machines from the same stable could and will be
entirely different. But I can't say anything bad about this
one.
