What makes you think phone support would be any different? I have been told different things by different people on the phone, do we demand in person support? What makes you think even in person support wouldn't lie to your face to get you out the door?
The problem is quality not formfactor. As long as people buy the cheapest they can support will always be cut to reduce costs. I just wish there was more pay per incident support that actually got you world class support and was cheap enough to be worth it.
