Welcome to
MacWorld. Making the switch is a decision you'll
never regret.
On my iMac G5 I'm running Office for Mac (heavy Excel user) and Mathematica with a couple add-ons for statistics and finance (
http://www.wolfram.com/ ). This stuff runs faster on my fully loaded Mac than it ever did on a Windows OS.
One complaint:
I bought my iMac with the Bluetooth wireless option. It never worked perfectly. When the mouse batteries would get low, the on-scren dialogue box would pop up, tell me the batteries were low, and then *poof* the batteries were dead.
Put in new batteries. Cursor stuck in upper left corner of screen, device not recognized ~ a problem that cannot be diagnosed without the mouse working or without a wired keyboard. Remove and insert batteries a dozen or more times until it finally works. I eventually gave up Bluetooth and now use both a wired keyboard and mouse.
One compliment:
All ~ repeat ALL ~ my experiences with Apple support have been great. Mostly it's been a matter of calling them up to ask, "How do I do this?" not, "I have a problem." They hire cool people and train them well. And, at least in the States, you don't get connected to India!
You're gonna love it.
