So that's not a real problem except the cost and time to find all the replacements.
Yes, there was a mention of running XP on the Mac, but the reason to move the Mac is gone. All the benefits that you have for moving to Mac vansish as you turn it into a PC. It will have all the same issues that had you looking at Apple.
As to hardware, be sure to check if they had the drivers or software ready for your leap.
I am a Windows PC user for about 12 years now and I recenty decided to play around the idea of migrating to Apple's Powerbook with Intel Dual Core. I have heard a lot about the compatibility of the two systems and am not sure whether I will have problems after buying Apple's Powerbook with their own OS.
At the moment, I use my laptop as follows:
Hardware: My usual peripheral connections are: Nikon digital camera, wireless mouse from Microsoft, Siemens M34 USB device for connecting and using my cordless landline handset Siemens S440 with Skype, Sandisk USB flash drive, iAudio U2 mp3 player, Motorola Rarz V3 mobile phone, internet connection using dial-up and in wifi hotspots.
Software: My usual software I use are: Office 2003, Acrobat Reader, Skype , MSN Messenger, Firefox, Opera, Windows Media Player, webmail, CA eTrust Internet Security Suite, and various software that I download from the Internet.
Based on the above, could you please let me know whether I should expect any problems if I migrate to an Apple computer? All my friends use Windows PCs and my computer at work is also installed with Windows. My main concern is compatibility of software and hardware rather than getting used to a mac OS. Could you please let me know what you think my most common areas of problems might be?
