I switched to a Mac Book Pro two months ago and now I seldom use my desktop. I thought I would miss the mouse but the touchpad is very nice. Yes, there is a learning curve but I don't miss the PC. I have one program (HTML editor) that won't run on the Mac so I still use the PC for that. The more you use it, the easier it will get. There is a Mac users group here in The Villages that is really active and and knowledgeable and will help you with any issues. Here's their sites:
