Yep I agree Keith. 8Gb just doesn't cut the mustard these days. I upgraded to 16Gb - the additional $200 odd dollars isn't too bad to be honest. In terms of resale, I generally run my computers until the die so I've never really worried about resale value.
One thing that I'm still unsure about is whether I'll be able to back up to my external drives that are currently hooked up to my PC. Is there a RAID option where I could partition the drive into two equal partitions (one to Mac format and one to PC format) so that it works in a similar fashion as RAID 1 (mirroring) but across two different formats?
That way I could use the drive on both PC and Mac and the same data would be available to both formats.
I'm guessing not but it would be nice.
