Lost my iTune downloads once (laptop stolen). I emailed iTune through Apple's customer service, and they got me almost all of them back through their archives. They allowed me to download back the whole lot, and were very helpful.
Now, people who talk about Macs with a smirk have usually never used one, or never been able to go through the few days it takes to "adapt" to one.
But one thing is sure, once you start using Mac, you don't want to ever have anything to do with a Windows based machine again.
Want an example? On a PC, a hard reboot is Ctrl+Alt+Del. Toddlers know that before they know how to say "Ma-ma".
A couple of months ago, I installed Windows on my Mac (have one 3D app belonging to Mr Gates that, how strange, cannot be had in Mac version). Well, the moment I started Windows, my computer crashed...
Now, the point is not the crash with Windows (no real surprise there!), but after running exclusively Macs for 6 years, I just had NO IDEA how you do a hard reboot on Mac. Never needed to do one before...
