I always used the Dell web chat to get warranty support and the vast majority of the time I just wrote a few sentences that made it clear that I was a power user that knew what was likely to be broken, someone would get dispatched with 24-48 hours, and I'd spend less than hour on the whole affair (most of that time spent doing something else while the support person replied or the tech worked on the laptop).
I have an XPS 13 and when my keyboard got flakey a repairmen came to my house and replaced the keyboard without even checking it first. Also, after I bought the laptop they randomly put $50 in my credit card account because I was "a good customer". WTF? I guess buying customer's loyalty is a thing now.
Compare that to all the terrible customer service news from apple, and I think apple is really the one that needs to change more the the other guys at this point.
