Way back in this thread, I speculated:
--Apple was not going to ditch & switch PPC chips/MBs for Intel chips/MBs
--Rather, Apple would offer a CPU option (Intel-based or PPC-based) on Apple's computers, as appropriate.
--That OS X 10.4 already runs on Intel-based CPUs
--That OS X 10.4 (for Intel) will only run on Mac/Intel boxes or those configurations that Apple blesses (licenses)
--That Apple has (or will) recompile and tweak Apple-branded apps to exploit either/both CPU options
--That Apple has Integrated QuickTransit into OS X 10.4 so that existing 3rd-party Mac apps will run on new Mac/Intel boxes an 80% full speed (the dip may not even be noticeable)
--That Apple will provide tools to assist developers to port their apps to run 100% on both CPU architectures as single Fat binaries
--That the same process could be used in reverse from Intel architecture to PPC architecture
--So, developers on either side had potential new markets for their products with very little effort.
The big gotcha, was (I thought) that the apps on both sides had to run on Unix/Linux-- the technique could not be used for wintel apps.
I speculated that if QuickTransit could be extended to encompass wintel apps that:
--Current wintel apps running under OS X 10.4 with QuickTransit on a Mac/Intel box would run, without change, at closer to 100% (no need to translate the CPU instructions)
--Current wintel apps running under OS X 10.4 with QuickTransit on a Mac/PPC box would run, without change, at 80% (the dip may not even be noticeable)
If this were true (QuickTransit for Wintel) then there would be a set of hardware and an OS that could run all the current Mac and Wintel apps, without change, on the CPU of your choice... without all the maleware baggage of the windows OS.
That was/is a big
IF!
While, in my gut, I felt that QuickTransit for wintel was a done deal, I couldn't find any reference to (or even any discussion of) running wintel apps on OS X via QuickTransit.
Well, this morning I found this link:

A silicon valley startup has cracked one of the most elusive goals of the software industry: a near universal operating system emulator which will allow any software written for any particular target platform to run nearly full speed on just about any other platform. This means that a program such as Autocad for x86 (Pentium chips) on Windows can be installed on a Linux box running on IBM's POWER 5. Or that Microsoft ACCESS for Windows on Intel can run at full speed on Mac OS X on PowerPC.
Mmm... this gives me some confidence... maybe it is a done deal, after all!
