Win95 has new 32-bit pre-emptive multitasking but old 16-bit graphics code (among other things) that handicaps the system. Copland is in a similar situation since it is using old code also. In Copland, the Mach microkernel does not realize its full potential as it does in other OSs. : |> Why would the bright programmers at Apple handicap a "brand-new" OS like : |> that? : : Because they want to deliver it a year (or more) earlier than : Gershwin. One of the major components of Gershwin is the reentrant : rewrite of all the toolbox. Like I said before, Gershwin is what I am really waiting for. Copland is in the same league as Win95, roughly. Gershwin will be in the same league as WinNT, UNIX, etc... Tony -- ------------------ Tony Tribelli adtribelli@acm.org
