Yes, the rumours out from last year are finally become reality today: Apple has officially released its first line of Mac based on Intel processors (Intel Core Duo), MacBook.
I've always loved the Mac and having the possibility to have one of this wonderful machines to work with my everyday programs (such as Visual Studio, SQL Server, Office etc.) is undoubtely fascinating.
P.S. Obviously, they have Mac OS X Tiger preinstalled, but (although this is a great OS) why not install Windows after having one of this at home? 
Update: Despite some rumours, seems that Windows XP will not be able to work with these new Mac's models.
According to Apple SVP Phil Schiller, the new Macs may not be able to run current versions of Windows due to the fact that they will boot using the Extensible Firmware Interface (EFI), rather than a traditional BIOS. EFI was developed by Intel and allows a number of advanced features, including the ability to connect to the Internet from a command shell before the OS is loaded. Since EFI was developed after Windows XP, it's not supported by the current or earlier version of Windows (only the actual 64-bit Windows versions support it, but the new Macs are 32-bit).
However, the future Windows Vista will support EFI and so the hardware will be totally supported! A new reason for waiting for Vista...
