I feel your pain. I'm disappointed with my 9360 as I've had several glitches over the past 3-4 months and getting it to work properly with the TB-16 is worse. Especially since the awful BIOS updates.
In your case, Dell should have sent a replacement laptop after the first few tries where it didn't work. I've been buying Dells for the past 15 years but I just feel it's not the same company anymore. Part of me wishes I went with a MacBook instead.
Agreed. I've told my story to enough tech people, some decision makers, fellow engineers. I've seen a lot of tech peers have spread that news around and seems like more Macbooks and other brands being purchased for corporate use. I wouldn't normally have considered the walled garden of an Apple product but headed that direction. Dell is too big to care...as a dissatisfied customer I realized I can cause some disruption on the ground. Would have been simpler if they gave me a replacement and kept me as a customer. Just spread the word!
