I really like the fact that Marian's query sparked some interest in (part
of) BG NOG community.
It would be great if more representatives of BG telcos participate in these

I have some negative experience with low/mid end Dell switches ( not F10 )
Almost half of our (access) network infrastructure in one of our Canadian
offices runs on Dell switches.
We inherited them from a company acquisition and slowly getting rid of
are not too bad if you use them as access switches and not doing too many
changes. Few of them died and now replaced by Cisco switches. The second
thing I don't like
is that they don't always play well with Catalysts.
I did exactly the same with Extreme and bought one of their switches to see
what ExtremeOS looks like.
Summit x250e-48p (PoE) for just $20 ! - bargain ;-)

You are right - network operators have a long way to go !
Unfortunately they are not as flexible as web centric companies,
like Facebook and Google for instance, which develop their own
hardware - switches, servers, NOS, etc
Bare metal/white box switches also appears to be very attractive to
Cumulus Networks in particular is one of the interesting players ( also
partnering with Dell ),
but there are also some hidden costs we must be aware.
