Hi David, just let me give some reply to your complaints, without the intent of a sterile discussion, to expose the point of view of Cisco when I was with them, as I don't think it has changed much now:
1. SDM is to be used just for the most basic configuration, anything else must be done by CLI . (Paolo's opinion: SDM is crap and should be avoided).
2. Firmware upgrades and support: It is not free. A support contract must be purchased, even in the initial period. The reason behind that is because the product, being a professional one, has to be installed by a certified cisco partner that has already the necessary knowledge and access to downloads and second/third level support.
3. QoS is absolutely working and as for many other things in networking, cisco was a leader in that. In you case, it was not configured.
4. Years ago, Cisco has aquired Aironet that literally invented wireless ethernet. Then again as provide the broadest range of support for securing wireless. Sorry, it requires training to be used in the full power.
5. Yes, many problems here, but many solutions too, and given for free. Compare to other vendors forums where you see "my router freezes under load and nothing can fix it".
Now, I think that any IT professional has spent time significant time on a product he/she was not familiar with. Usually, the result justifies the invested time. If that was not your case with cisco, is because you had zero exposure to IOS and undertook a task that requires significant experience and knowledge. Consider, there are professionals doing this for a living.
Anyway each one is entitled to his opinion and I wish you best luck. Come back here at any time if you need!
