An entire thesis from Darth on that subject might include cooler weather, but may also have to do with a certain manufacturer which, on at least two computers that I ever bought from that brand, tends to install hard drives that barely make it to the six month mark before trouble begins.
And so that nobody will complain about their wonderful company being singled out, we shall simply say what an old car mechanic said years ago. "You can't take it personally, Miss Silkie; they're all pieces of %*^@. See my brand new Continental over there? It's pretty, but it's a piece of %*^@ that is here being fixed. Same with a Jag or a Rolls or Mercedes, a Chrysler or a Chevy. They're all Edsels, Miss Silkie. Money buys them, and money fixes them. You have an extended warranty, so you already paid the money that fixes it. So please stop bitching. Thank you, Miss Silkie.". I loved that old guy. A refined grease monkey. LOL
