Harvey Nash runs Macs as well as PCs, and Behenna said he sees no compelling reasons to move more toward Apple's hardware at this point. But he added that he will watch the development of Boot Camp.

Apple itself said that some Mac features won't work with Windows XP because of hardware incompatibilities. That includes its USB modem and its remote control, wireless keyboard and mouse.

Boot Camp is available now as a free download and will be included in the next major release of the Macintosh operating system, Mac OS X 10.5, code-named Leopard. The release is expected late this year.

In a statement, Microsoft said it is 'pleased that Apple customers are excited about running [Windows], and that Apple is responding to meet the demand.'
