Just intruding here to offer my thoughts. I only use a Windows PC and have never used a MAC, but if you are willing to try I bet that, in time, you will love your MAC. This is the message I hear from many who have switched.
Yes it will take time, but that is true of any new computer systems. Just cast your mind back to when you got this new Toshiba. If you had a PC before, was it very different to that? If you were new to PC's then that was perhaps an even greater learning curve.
I can't say what you should do, but others here will tell you more about MACs, so I hope they help you come to a decision.
In the meantime, if there are any problems you feel the helpers here can assist with your current PC problems, feel free to ask, in one of the Windows forums, or the Computer Help or Computer Newbies forums. They are listed in the column on the left.
You may find Grif's now comprehensive, "A few tips for Computer Newbies" thread useful.
I have read many of the posts about MACs vs PC but for me I still need an answer about the problems that come from knowing PCs well and knowing nothing about how MACs work. How complicated are they compared to my PC laptop?
My granddaughters rave about their new MAC laptops and tell me "you will love it" and then add "It will take you months to learn." They think I am 'technology challenged' & on some things I am.
I find that "housekeeping of my PC laptop" takes more time than I like. My current laptop is a a Toshiba Sattelite XP 2005 and has problems. My Outlook Express has changed, PC taking too long to boot and I can't always get connected to a web site. My Time Warner tech guy suggested getting an estimate, as he didn't know what all was going on. But he felt that it was time to buy another laptop.
So what will it be a MAC or a PC?
