A MacFixIt reader had a very interesting email exchange from Psystar's support, who told him that they don't want customers installing Leopard themselves. Here's the quote from the support team:
We absolutely do not support customers attempting to install the Leopard operating system on our Open Computer themselves. This is due to a difficult process that we go through to get Leopard to function on our computers. We encourage you to purchase an open computer, and select the option to have Leopard Pre-installed. Currently, (shipping the computer back to us) is the only option available. If the HDD dies, you can ship it to us for $50 plus shipping, so we can replace it for you.
Good luck to anyone buying!
What do these wankers want to be able to trawl anyone stupid enough to buy one for any personal info. eg: credit card, bank or other info they could use to rip the unspecting idiot off with.
A simple system update will be more than enough to kill off them for a start.
If anyone has taken the time to closely read their website front page there is little to any info about osx mostly all windows crap. Most of which would probably make windows worse than it already is.
