To me it appears that Lion will provide considerable support for Applications from Developers.

Worth looking at:

'Versions' : Browse versions. Side-by-side comparisons.

'Text': more languages.

'System Preferences': Scroll direction Preference - Wow.

'Screen Sharing: More secure.

'Safari': Major changes.

'Multi-touch Gestures': Heavily promoted for MacBook Air users.

'Mission Control': New.

'Mail': Total rewrite it seems.

'Mac App Store': I'm not sure you can get a DVD but to install Lion directly you need to go to the App Store but you can't do that is you don't use Snow Leopard. Bit of a Gotcha here.

'Launchpad': App launcher

'Accessibility': Big increase in VoiceOver, braille, etc.

Conclusion: The Mac is mot going away anytime soon.

How will Nisus Software cope?
