That's another reason I like buying computers from Dell and other reputable online computer vendors. They do their own tech support of the systems they sell. They can provide one point of contact when there are problems with interactions of devices from multiple vendors. I prefer online tech support, because there is a record of the support session afterwards that is available in the future. I can save online chat sessions to a file on my computer for future reference or save emails.
I bought a TV from them in 1997, it was still working in November, but I replaced it with an 1080 HDTV.
I’m not software literate so I like that I can take my laptop to someone who knows what to do when problems arise. I would prefer to purchase online but I’m screwed if the puter acts up.
