> The whole web 0.1, 1.0,2.0 came from the fact that PC clones were everywhere

I was there and it didn't! TBL did development on Next. There were some text mode browsers that worked on Unix only. The popular graphical browser was Mosaic[1] which started out as Unix/X windows only. It was run on Sun, HP, IBM, SGI etc workstations (32 bit).

At that time popular Windows was still 16 bit. It didn't even include TCP/IP with various third party stacks (for a price) and later a Microsoft stack for Windows 3.11 for Workgroups. Some brave people did start porting Mosaic but it was hard because a completely different GUI API and semantics was needed, as well as dealing with the cramped machines compared to the 32 bit workstations. It was late 1994 before these ports became somewhat usable.

Netscape was formed around then, and the big difference was they made their code portable to multiple guis from the very beginning (a lot easier than retrofitting it). By 1995 every platform had to have TCP/IP and a web browser to be relevant. The web spread because no one was in charge, and everything had to work everywhere on a wide variety of screen sizes, operating systems and user environments.

ie it was the diversity of systems out there that was the cause, not that you could buy the PC architecture from different companies.
