Query: Don't buy if you have a front-loading CD/DVD driver (e.g. Powerbook)

The installation software comes on a small-sized CD which any front-loading CD/DVD drive can not handle (and will break your laptop). Luckily, I called tech support before inserting it into the drive, because I've since heard of others who had to find unusual ways of getting the small CD out of their drive.Also, the accompanying instructions are minimal at best. I'd avoid!
