Sorry to barge in on your board but as a recent SilverJet convert,I'm now a fairly regular passenger and thought you might like to hear my opinion which, of course, relates to only a small part of the issues you are discussing.
After spending years flying with BA and then deciding to move to Virgin, I decided to try SilverJet for the first time earlier this year. As I have a US office close to Newark the routing was perfect for me. However, this was not the main reason for changing. I was tired of the hassle (at the time) of Heathrow, tired of the reducing service levels in VS and, quite frankly, wanted to fly in a quieter less rushed environment. Nothing, I can assure you, to do with the ticket price or being a "business class wannabee". To be honest, I and twenty or so of my colleagues who also now use SilverJet would happily pay the same or more than current J rates for the above advantages.
Of course there are some minor niggles but I think we all have been very pleased with the quality and service experienced from your company.
I still fly VS for all the other places I have to go to and in my opinion, Silverjet service has a considerable edge although the, to my mind, rather onerous back to back flights do explain some comments about a few return trips.
And the bed? Well, OK it's not Flat as in "horizontal flat" but it is flat as in "smooth flat" and I actually quite like it
Sorry if I have entered forbidden territory but I am sure Tightslot will excise me in an instant if I have strayed to far.
