How about Ethernet vs Token Ring?
David - coming across your blog and GC's uber-blog for the first time today thanks to Andy at Nyquist Capital. Really enjoyed this post and the others. Regarding your post, while many of the people in the industry are engineers and claim to focus only on objective facts, the truth is that engineers are humans and get emotionally involved with their work - and religious about their protocols - then defend them with 'facts'. Ethernet is a survivor - partly based on the excellence of the original work and partly based on 'marketecture'. Ethernet today is nothing like the original IEEE 802.3 10Base5 CSMA/CD approach, but it remains cheap, works well and is backward compatible with most everything. Cheers Mark
