Max out your RAM.
Parallels.
Buy a bluetooth Mighty Mouse for your laptop bag.
Look for David Pogue’s “Missing Manual” for switching to the Mac.
You might want to wait until Leopard comes out – unless they offer a free upgrade from Tiger with new machines now. (kind of like buying an XP machine two weeks before Vista came out).
Get RemoteBuddy ($10) if you want to use the Apple Remote for anything useful.
Don’t waste time or money (like I did) messing around with QuickTime – that’s one of those annoying things where Apple tries to milk you for every penny (only recently did they cave in and allow full-screen mode in the non-pro version). Download the free VLC player instead. It’s free and it’s much better.
Definitely inventory your Windows apps and see if you can find a Mac alternative for each one. In a perfect world, you will. Don’t forget all of the little stuff you do (e.g. I use a right-click “copy path” utility to copy file paths to my clipboard. How do I do that on Mac?)
Do serious investigation on syncing with a Mac if you use a Treo or some other such device (can you find all of your apps and conduits?)
I think wasson has a good idea, but it is pretty darned hard to make the switch, just like that. And there’s always the issue of repurchasing software. I wish I had Photoshop for Mac, but I can’t justify buying it, as I already have Photoshop 7 for Windows. I did buy Office, however. I depend on MS Word, so I refused to have to go to Windows for that.
Besides, it’s absolutely geeky cool to show your Windows co-workers the magic transformation from Mac to (real, not watered-down, not emulated) PC at the press of a key.
In some cases, I have found better alternatives: I was using MindJet’s mind mapping software in Windows, but I eventually realized that the OmniOutliner that came with my Mac was better suited to the exact kind of work I was doing, so I don’t have to go to Windows for that one.
As a proud MacBook Pro owner, I must be honest and say that there are things that you will find missing – it’s not all perfect and rosy. Two simple examples of annoying stuff that a Switcher might notice: Windows has better keyboard navigation support; Network drives work more smoothly in Windows (at least my Samba shares from Linux).
Nevertheless, for every annoyance, there are two cool features. Example of one of my favorites: Mac’s talk PDF far more fluently than Windows machines do.
That said, you’re going to love it. These are fine machines and worth every penny.
