Read something somewhere in some forum about the error correction being structured in a way that could cause some serious lag time were there ever to be an error on the drive.

Unfortunately it was in a mad dash to absob as much info about the laptop market as possible and I didn't save the link.

Wound up getting a pretty pimped out Dell Inspiron 6000

2 GHz Pentium M
15.4" Screen
1 GB RAM (Single DIMM - so getting that extra 1 GB more wont' be so hard)
60GB 7200 RPM drive

Next stop : RME Mutliface II
