Been a lifelong Windows user. I am going to be purchasing a new computer at year's end. I am very curious about moving to a Macintosh. Every Windows user knows that Macintosh is the superior computer with the superior operating system. I use my computer on a daily/hourly basis as it has become an integral part of my business and life. I'd like to move on to a platform that is more professional and efficient than what I have been using all my life. A few things bother me about Macintosh.... First, the price. If I were to buy a Macintosh G5 (and I want the best) I am already opting to spend a lot more money than I would on a top-of-the-line Windows PC. Secondly, the fact that I have hundreds of Windows-based software that may or may not play under Macintosh bothers me as well. I have heard that there is a program that allows Windows programs to play under the Mac OS, but I also heard it can be slow. So, a few questions.... 1. If I am going to use the computer mostly for surfing, email and photo/video/audio editing programs, is a Mac G5 overkill? 2. I see most G5 computers tout 512 memory. If I were buying a Windows PC I would opt for at least 1 gig. Is 512 memory on a Mac comperable to the same on a Windows PC? I will be using a lot of high-memory programs and startups. 3. Are there still a lot of software that will not work with the Macintosh? For instance, even chat cliants like Trillian or email programs made by 3rd party vendors? 4. Can I work with .JPG .GIF and .BMP files in Macintosh or am I now going to be working with an entirely new array of file types? 5. What program allows you to run Windows programs under Mac? Will it run any Windows complaint software? How much slower will it run under the Mac environment? Can I run the Windows client and multitask with Mac programs outside that client at the same time? 6. Is it easy to migrate from a Windows XP environment to a Macintosh? In other words, within a few hours of use, will I pretty much be comfortable navigating around the Mac OS? 7. A top-of-the-line Windows PC costs about $3k or so. How about a G5 with lots of memory, high-end graphics, a DVD and CD burner, TV card, (and perhaps a few other bells & whistles) cost? Note: I don't need a Monitor 8. Will my Linksys adapter automatically configure to the Macintosh settings once I turn it on? I'd hate to have to reconfigure my entire wireless broadband network. 9. If I switch to Mac will I regret it? Will I miss Windows? Will this be the best move I will ever make? A lot of questions. Answer what you want. Feel free to arm twist me away from Windows. Very much appreciate the advice in advance.
