I'd probably prefer the latest FreeBSD on a new intel processor. (not proprietary - equivalent technology).
Ditching Motorola and then IBM to replace them with Intel essentially removes what was unique about Apple. The differences will be purely cosmetic and continued sales might actually be endangered by these changes that have removed much of what created Apple users brand loyalty.
Dell building Macs? SHUDDER... so much for mac performance and quality. (Dell = crap in my books, ceape3st parts, ever corner cut... check the caches available on the cheapy "product dumped" processors used by dell - its laughable.)
While on the subject - ITUNES IS A TROJAN on windows systems. I had a devil of a time figuring out what had crippled a friends machine, until I had found ITUNES using 100% cpu which was not cleared with a reboot, the condition persisted for days, until I identified it and uninstalled ITUNES. (Thankfully it did uninstall, so I guess it's not really a trojan, but it sure behaves like one).
