GoToMyPC, probably the most-advertised solution for remotely accessing your other machines, is finally coming to Mac. No, it's not called GoToMyMac. The slightly-more-confusing name is "GoToMyPC for Mac." Despite the name, you can use it to access either a Mac or a PC from your OS X machine. The pricetag is $19.95/mo to access one other computer, but there's also a 30-day free trial. That should come in handy, because GoToMyPC is a popular brand-name product debuting on a platform where there's already some solid competition.
The first alternative that comes to mind is Apple's Back To My Mac, which is part of MobileMe, and is also no good to you if you're looking to use your Mac to access a Windows machine. There's alsoLogMeIn, which comes as either a free or a Pro version (Pro costs $69.95/yr to connect to one computer but there's a 30-day free demo). LogMeIn also has an iPhone app, and there's evenBlackberry Storm support (seriously). If you're just looking for simple screen sharing, LogMeIn Express is a free option you should explore.
