Personally, I've never had to deal with Dell CS because my Dells have always worked.
Our office currently has 2 Dell desk tops as well as a note book. We also have a Dell data projector. All work extremely well and are much faster than other brand computers I have used.
In a previous ministry position, we had 2 Dell desk tops that never had any problems either.
On the other hand I've used 2 Toshiba notebooks that were junk. Continual problems.
My only real complaint with Dell is that the machines that they have on sale at low prices never have had what I needed in the way of software and features. I've wound-up buying a more expensive machine that way. Maybe that's why I've gotten good results . . . you usually get what you pay for.
If I can afford them, I'll continue to buy Dells.
Every blessing,
