Cisco

Stability - no one is going to buy Cisco any time soon (though there is still attrition).

Incredible wealth of resources available. Lots of super-smart people running around. Lots of market share in virtually every product line, and the cachet that comes with the Cisco name.

Huge company. Too many competitors with better technology. Cisco can't be expected to turn on a dime, but the products need to ramp faster.

The whole "end to end" argument is getting stale with a lot of customers. We need to innovate in areas other than revenue and market share, or both will ultimately suffer.

Innovate. Product cycle times have to improve. The "Advanced Technologies" are at least 1-2 years behind much of the competition.

Also, quite a few of the products have a lot of buggy code. Entire releases are to be avoided because of instability. Many customers have to make the difficult decision between "new, needed features" and "stability" far too often.
