I think it should last quite a lot longer.  I have an 18-month old A21p,
and the battery lasted around 3 hours when it was new.  It has dropped
considerably now and I am getting a new battery since I think this one
is basically stuffed - I only get 1.5 hours max now.

Not sure abou that.  I only ever boot when I am on AC power to try and
limit the side-effects of speed changing (last booted on 23rd May) and I
see no change in /proc/cpuinfo regardless of whether I am connected or
not - I assumed it was calculated at boot.
