How Apple can catch up with Linux

There are two elements missing from Apple's Mac OS X desktop environment that set productivity under Linux apart:

1. Paste action of middle mouse button (yes, Mighty Mouse is the right direction).
2. One-click responsiveness of windows not belonging to the currently active application.

Finally, Finder really needs a big update now that encompasses Spotlight functionality (more file info in Spotlight, instant conversion of Spotlight searches to Smart Folders), but I believe this is in the works for Leopard already.

Finally, by making Windows apps run on OS X, or OS X apps on Windows, Apple could grab some of the Windows-entrenched niche markets such as those tied to Windows-bound GIS and CAD applications and traditionally relying heavily on superior workstation processing power.
