Are you seeing a more competitive market for services?
I think, probably yes as more players have tried to come down from applications and some of the resellers are trying to move up into services. I think there probably are more players. What helps us is having scale in both services and in products over and above some of the competition. ... We have a very big sales force of technicians, which new entrants find hard to replicate. It doesn't mean they couldn't acquire and it doesn't mean they won't build it but in terms of uniqueness, it is an infrastructure supply chain, it is a sales force of the best employees. We're only focused on infrastructure, that's why we do it well. It's not one of many businesses that we try to do.
