2. No good quality free software, you had to buy everything from Oracle/Microsoft/Netscape to get a decent website up and going. Licenses cost a lot.
3. No lean startup model everything was a big bang approach which meant a lot of cash needed to get version 1. out.
4. No stackoverflow/google etc. so it just seemed to take longer for engineers to build something. Debugging took longer , the programming languages were less mature etc.
Put all together it is about a 100x reduction in getting something in front of users today.
