Whether or not to buy this program comes down to a choice between great features and annoying bugs that Microsoft has had nore than enough time to correct, unless it just can't keep up with Apple's changes to its OS. Various forums report crashes, which I've also experienced, e.g., when trying to configure the toolbar in a way that involves dragging any button OVER another that has a "field" (such as font, or page view percentage). A File menu item called "Send to" is supposed to allow you to neatly coordinate your .doc file with your email client so you can send the file almost directly from Word, but I found the required submenu item grayed out, even though my email client is on the list of accepted ones, and is configured correctly. There's nothing in the program's Help file on this, which is at best adequate. Apart from some relatively low-level instability and quirkiness (buttons that were working fine in the previous session are sometimes suddenly grayed out and unavailable for no apparent reason, and need to be manually reconfigured), Word probably is the most powerful and intuitive word processor for OS X out there. Mariner and Mellel are still very limited. Nisus Writer is really very much in beta with many bugs of its own, and the cheap alternative (ThinkFree) doesn't provide guaranteed MS .doc compatibility). So, while it obviously depends on what you need to do what you do, in the less-than-perfect world of software, where not-as-advertised has become the de facto standard of "ex-sell-ence," Word is probably a good bet. I would look for a bargain though (under $200 on Amazon at the time of this writing). Best to all. PG
