What are other arguments against vendor lock-in ? Is there any argument FOR such locks (please spare me the support issues, if you can't read specs and SNMP, you shouldn't even try networking) ?
Did you ever experience a shift in a vendor's position regarding the use of compatible modules ?
In the case of some vendors (yes, you again, Cisco), the shift has been in the wrong direction. Some vendors treat optics as just a tool to do a job, and price accordingly. Those vendors tend to have fairly relaxed policies re: working with non-$vendor optics, as well. Other vendors treat optics as a cash cow^H^H^H^H^H^H^H^Hprofit center, and also price accordingly. Those vendors tend to scream bloody murder if a non-$vendor optic is encountered. Beyond that, I'd say you've covered all of the logical reasons why vendor lock-in is a bad idea, but as others have mentioned in this thread, those attitudes tend to change at a ridiculously slow pace, and only when forced by market conditions. jms
