Ahem,,,
RISC OS for me pls, closely followed by OS/2
Bit of useless info for you folks...
OS/2 was jointly developed my MS and IBM to be the successor to DOS ie true 32bit multitask blah blah OS...etc...
Until they had a massive fallout over the GUI, Microsoft wanted Program Manager and IBM wanted Presentation Manager.
So they went separate ways......they both owned the code so......
IBM went ahead with Presentation Manager and released OS/2 to the public
Microsoft stuffed Program Manager on the OS/2 kernal called it Windows NT 3.5 and released that......
Through all revisions of Windows NT right up to Windows 7 exists chunks of the OS/2 kernal, NTFS of course is the IBM HPFS a la OS/2 renamed and tweaked....
Guess OS/2 is still with us in some shape or other....
Sad innit, have Microsoft ever produced anything of their own entirely from scratch.....NO
