"InfoWorld's 'Save XP' petition asking Microsoft to keep Windows XP available indefinitely, not end most sales on June 30 as currently planned, has prompted many readers to suggest that maybe the best answer for those who don't like Vista is to switch to another operating system completely,"

"Of the plausible alternatives to Windows, Apple's Mac OS X has the largest market share and history. InfoWorld chief technologist Tom Yager has written that the latest version of the Mac OS, Leopard (10.5), is simply the best operating system available. And Macs are indeed popping up more frequently even within IT circles -- I've seen more MacBook Pros in the hands of CTOs and IT execs at conferences in the past year more than I've seen Mac notebooks in such venues ever. Although there are no real numbers on just the business adoption of Macs, it's clear that Apple is in growth mode, gaining an increasing proportion of all new computer sales for more than a year now."

"InfoWorld's Yager has chronicled the adventures of one PC user who switched to the Mac OS, showing that for an individual, the conversion was ultimately a rewarding one. The TechWeb site has also provided a good guide on how to make the switch to Mac OS X."

"A key tool for any Mac OS X switcher is a virtual machine to run Windows for those apps and Web sites that require it. Both Parallels Desktop 3.0 and EMC VMware's Fusion software will do the trick, as InfoWorld's comparative review has shown."
