My Z06 will be at NJB Automotive. They have storage now. Climate controlled, alarm system, insured, etc.

I believe it is $100/mo.
I use Macs and Windows PCs every day. To get crap done, I will always reach for the Mac. To surf on the couch, I reach for the mac over our Dell. I vote macbook pro 15" with a SSD.
So I got the Ultra TV setup and it seems decent. The interface can be a bit unresponsive at times but, the best feature is the PC connect. From any TV you can pull up your computer and play videos in the Movie folder. It has to be WMV so I am in the middle of converting a bunch of stuff. AVS Video Converter has been solid so far.
