Tools are tools
It´s fairly easy to say that I use Windows XP about as much as OSX. Mainly because there is no Adobe CS2 Universal suite . I checked the PS-CS2 speed difference on my MBP17" with 2Gigand a 100/7200 disk+an external LaCie Triple extreme 500 as swapdisk (see other thread here in the forum) and the Win version took 2.25min whereas the Mac version in Rosetta took 5.30min. I do a lot of imaging work and the new glossy display is able to be calibrated to a DeltaE of 0,40 , that´s amazing for a notebook. I made several ICC´s with D50,55 and65 for Win and OSX and compared them, they are nearly identical, so I can use the different OS´s seamlessly. Many of my language tools (lingvo11) run only in Windows, some other progs (Aperture) run only in OSX -so I find both extremely valuable. I do support for both platforms and now I need only one machine to take with me - THANK YOU APPLE !
