The only apple product I own is an ipod touch, I wouldn't have owned it if I knew it's registration required too much personal information.
Apple products are simply inferior at every price point with the exception of the ipad2. It seems most of the people who own macs aren't very computer savvy and don't know that there are tons of free antivirus and antimalware programs out there for windows (for those in IT that posted here speaking about the cost and maintenance of their own machines, they must have their jobs based on nepotism instead of real skill). Most people who own macs live in a false sense of security not realizing that the main thing to worry about are exploits and apple is always the first os cracked on any security contest or conference. While I like the looks of most apple products, I can't justify buying it at those price points due to it's lack of performance.
I use Windows and Linux, but I have tried apple in the past due to relatives owning them. When I hear about people speaking about speed comparisons between the two platforms in most cases it's an apples to orange comparison, they buy a new mac which cost more than their old pc, would it be fair to use a mac for 7 years that was 2k in the past and compare it to a 1k windows machine now? Well why not compare a modern version of both at the same price, take both of them home, test them for a week, and bring back the loser. If you want real speed use some of the low footprint linux distros that resides in ram drive, windows and mac will both seem to lag compared to them.
