My experience with tech support from Dell and other large vendors is
contradictory to yours. Even when I have "on-site" support, they will
not send out an on-site technician until the problem has been accurately
pinpointed through phone support, so they know what hardware to ship.
Most recently, I had a Dell PowerEdge something-or-other that wouldn't
bootup - it was competely dead. The phone technician had me on the phone
for several hours diagnosing the problem, and LONG after my day normally
ends. I asked the phone technician to just send out an on-site
technician repeatedly (and pointed out that we are PAYING for that
service), and he refused.
After finally diagnosing the problem, the phone support then scheduled a
technician to come out with a new PERC card and motherboard to replace
one or both of them. At that point, they could have skipped the on-site
technician and let me replace those parts myself. When the technician
showed up a couple days later, he was in and out in less than an hour.
Again, I'm not picking on Dell specifically. I've seen this behavior
with other large vendors. My point is that "on-site support" usually
isn't always, so don't believe the hype.
