Okay, now that you have justified the Mac to yourself, do you want to get
your broke Karmic working? ;-)
Your problem definitely sounds like a Grub issue based on my experience.
Interesting on the Blackberry. Last weekend I borrowed a Sprint Aircard and
I had it working on Karmic in about 4 clicks of the mouse. Very painless.
Out in the backwoods of Michigan speedtest.org said it had .7 mb/s down
and .31 mb/s up. I was impressed. I know another who uses an Alltel (now
Verizon) Aircard on Karmic and he is able to do Cisco VPN with it also.
What email client do you use? I find good compatibility between Evolution
Mac has a VM in it and I have helped someone load XP into it so they could
run a Windows app. (see I helped justify the Mac even more. ;-) )
