Been using a PC for many years. My 3rd PC is about to die....or at least Windows is. I do not want to continue with headaches, and I'm hearing that Mac is the cure. My main use is for a home based business and personal use. Will definitely need to bring over my QuickBooks database, but prefer to buy new Quickbooks software for MAC rather than trying to run my PC version (it's old 2003). Need to be able to use Excel and Word files. Again, if I can use existing files in a Mac Version of Word/Excel (does that exist?), then I prefer this over trying to run XP. My XP version was an upgrade and I prefer to TRASH it and start clean with all MAC stuff if that is possible. Really don't want to recreate all files and docs on Mac - can PC files be opened in Mac Office type software? Of course, need to be able to get e-mail. I'm assuming there is email software included..... I don't really understand all of this "parallel" lingo or partitioning drives to run both, etc..... Oh, and for what I'm describing for use, is 1GB of RAM enough? I have 512 on my sick PC and it takes minutes to open programs....but again, it is terminally ill, I'm sure. No gaming planned. Would love to be able to convert home videotapes to DVD down the road, so expandability is great. I have a monitor that is new (17inch), so I think the MacPro is what I need. But, I am not sure about any of it. Software advice is appreciated too. Pricing, of course is a strong consideration, but so far comparing a new Dell to the MacPro (true specs), it appears that the Mac is not really that much more. Oh....I can only dream of what it will be like without Windows Updates......... HELP!! I need to make the right decision - and being proficient in Windows and not in MAC makes me uncomfortable. Can anyone shed some comforting light for me?
