I'm speaking of being able to hover my cursor over some text and typing Control-Command-D to bring up the pop-up dictionary. Having an Open In Dictionary option in the Control-Click contextual menu. Even access to that awful looking Apple Fonts palette because I do make sets of font in Font Book and I cannot see those sets in ID's font menus. How about access to the Character Palette in the Edit menu? Do I need more? Yes! Why does the new version of ID default to taking up the entire screen as a Windows program? This is not the Macintosh way, I think.
Microsoft learned their lesson a long time ago when they released a version of Office that they bragged was exactly the same as the Windows counterpart. Well, it was very, very slow to launch and I think it sold miserably. After that, they have gone out of their way to produce Mac-versions of their programs, I think, even having that Mactopia website for a while. I wish Adobe would learn this lesson, too. Besides pricing CS4 upgrades awfully high, I think, same as Windows approach is one of the major reasons I will not upgrade to CS 4.
