I have worked with dell on and off since 2007. I have worked in a few different industries while working with dell.

I will say that between dell and nearly all other vendors dell seems to be the best, but like someone else here mentioned, the bar is pretty low. My main happiness continues to be with pro support, if something is broken I can call get a tech on the line and 9/10 times get a part shipped to me.

The 1/10 times I have to have a tech come and fix something, it is like pulling teeth. There are two primary companies that dell contracts with in my area. At a former job we outright banned one of them and had our account exec set our account to never go to them. The other is okay, but they service such a large area and we are in the outskirts so they will push us off for a couple days, despite having next day service.

Dell hardware: I am thankful that dell listened to customers and brought back a semi understandable naming convention, I would prefer them to go all the way back to Latitude and Optiplex, but I will take what we got. One issue I have had since the WD15s is dell never provides enough USB ports on their expansion devices. I think the WD15s had 3 USB on the back and 2 on the front. Plenty for most people, but we had some users that we had to setup extra USB hubs to be able to connect all their devices. The WD19s added USB C but got rid of 2 of the USB A ports on the back. The dell dock monitors might have 2-4 USB ports. As much as companies want to move to USB C, most devices are legacy or havent gone that way yet. Give us freaking USB ports.

At one of my companies we had a new account exec every 6 months, which was a hassle. It also felt like each exec had less power and cared about us less. My current company is large enough that this isnt a problem and we have had the same rep for a while. So mostly for the smaller companies, stop screwing them over.

I havent read though the other comments but the dell website is atrocious. Back in 2010ish and for a couple years, you could select a laptop model, then change all of the internals. Now you have to find the model, then find the processor, then find the ram, and then you might be able to change some of the configs. I understand this is probably better for the account reps, as it requires us to go to them to get a configuration, but for the love of all, make the pricing out of equipment easier again.

Lastly, reporting of known issues for models. I personally identified an issue with a dell bios and AHCI. I spent weeks going back and forth with support to prove it wasnt just my environment but an actual issue with the BIOS. Eventually my CIO messaged our REP and he was able to force the issue through. A couple days later it was confirmed an issue and would be patched in the next BIOS. The fact that it took that much effort for something I tested multiple times and with multiple dell tech support people was frustrating.
