Overall, the Apple keynote has me worried. All the Apple operating systems, and essential apps, are far too buggy, but instead of addressing all the bugs Apple is choosing to make dramatic alterations in their systems’ appearance and, in some cases, behavior. Maybe they’ll stamp out bugs along the way but my fear is that these releases could become a usability nightmare. This year really needed to be a ‘Snow Leopard” year, a year for fixing problems rather than adding features, but Apple has taken the opposite approach. I won’t be installing any betas of these OSes.
