I've just purchased a new Dell Inspiron 3670 with Windows 10, i5+8400, 8 Gb 2.7 MHz ddr4 ram + 16 Gb optane memory cache, 3.5" 1 Tb 7200 rpm hdd, which won't arrive for several weeks. I declined the extended maintenance contract providing at home service, as I often do (although I have used them on occasion for more fragile devices such as printers) since they only cover up to 4 years, and usually problems develop after that time. The computer comes with the standard 1 year warranty, but Dell said that if there were a hardware issue during that time, the whole unit has to be sent back to them, obviously a great inconvenience meant to encourage purchase of the contract. Do you agree with my reasoning to let the contract go? Would a big box manufacturer use a lower quality part on a computer without the extended service contract compared to one with a contract? Thanks for any advice.
