Here's the thing... The company I work for has a few sister companies in HK and China. I work for the U.S. office.
We recently (last year) upgraded our switches in the U.S. office. Previously, we were running 3Com switches of various types and models (3300's mostly of different kinds, and some 4200's). The decision to replace them was due to the fact they were getting old and the performance wasn't really there when you start daisy chaining 10 different switches to support over 200 ports.
When looking for new switches, I looked at Cisco and HP. Our overseas IIT guy tried to get us to go the 3Com route once again, since that's what they use in the HK and China offices. Actually, they use Huawei branded switches as well as 3Com braded switches. If you don't know already, they're basically the same thing. He really tried hard to get us to go that route, but I would not budge. I did everything to show that 3Com had very little market share in the U.S. and thus very little support.
Anyway, we ended up replacing the aging 3Com equipment with HP Procurve switches (5406 and 5412). We wanted to go with Cisco switches at first, but they were our of our budget. Next to Cisco, HP seemed like the most logical choice.So far, I'm happy with the decision.
I just find it ironic that after the acquisition, that whole power struggle over which switch to use will be moot.
