Think Secret have been able to have a look at the first few of Apple's Intel-based Mac development kits. Their article has some pictures of the machine running Windows XP, but it was not without some hassle:
The only misbehaviour sources encountered involved the video card. Initially, Windows refused to budge from an 800x600 setting on a 23-inch Cinema Display. Some prodding managed to get the screen to 1600x1200, but sources were unable to get Windows to take advantage of the entire screen.
Of course trying to install Intel MacOS X 10.4.1 on a non Intel Apple results in a message stating that the current hardware configuration is not supported by Darwin X86.
On to some other news Macworld have reported that CodeWeavers will be supporting their CrossOver Office on Intel MacOS X.
