Speaking of more spindles, does SATA address the usual IDE problem (system
has response hiatus (keyboard, audio) during intense IDE activity)? Sure,
SCSI, I know, don't have the budget for that one at home. No way how I could
pay half a TByte worth of SCSI drives.

Is responsiveness visibly increased in general in the 2.6 kernel family (haven't run
one yet)? 

(I mean, I don't expect hard realtime from a desktop/server OS, but even in
comparison to Darwin/OS X the usual Linux behaviour is terrible. Maybe my
systems so far have been pathological, so I'd be very grateful for
suggestions as how to fix them).
