Dell Computer Update

I got a call a few days ago asking how my computer was working. I told the person fine and hung up. Today I checked the number and it turned out that it was a legitimate call from Dell. I bought a Dell Tablet two years ago that was nothing but trouble the first 6 months I owned it. I have previously written here about it.  Dell repaired it 4 times and replaced everything but the case and screen eventually. Turned out to be a bad battery. It has been working well ever since. It gets lots of vibration etc. because I mostly use it mounted on my 4 wheeler for work. Since they finally got it fixed, I am very pleased with it, but it was a painful process. I am really surprised they called to check on it after all this time. Way to go Dell.
