I have been investigating changing from Windows to Mac. My main concern is the investment I have in windows software. I was surprised that Apple's web site did not have a help screen giving info on how to go about cross platform upgrades for the major software used by most people. I am a photojournalist and I have listed the windows software I use and the response I have had regarding a cross platform upgrade. Adobe Photoshop: 230 for upgrade from Photoshop 7 win to Photoshop CS Mac. Microsoft Office Pro: NO RESPONSE from Microsoft (what a surprise) PhaseOne C1 Pro: RAW photo processor NO COST !! CuteFTP: NO RESPONSE FotoWare: FotoStaion: Image Management NO RESPONSE I think Apple would get a larger market share in they invested some time to research how to get a cross platform upgrade and listed the info for people who cant find out and just give up.
