it was as tricked-out as i could go without bending the case: the 32mb graphics card, 1.5GB RAM and a 1.4GHz powerlogix processor upgrade. it lasted me from christmas 2000 through to may 2009, when i finally bought an imac to replace it, and handed the old girl over to mum & dad to write emails on. 9 years of useable service is not too bad, even for an expensive initial outlay.
it's a shame it didn't quite get some of the advances apple made soon after: integrated bluetooth & better wifi to make it almost completely cable-less, for example. i'm sure that was in jobs' original plan.
