Two years ago I bought an XPS one 2710.
I upgraded to windows 10 no problem
Last October the machine suddenly stopped.
Today, after numerous attempts at fixing it, they called me to tell me the PC cannot be fixed and that basically I have to throw away a 2000 euro PC after two years. 1000 euro per year for the priviledge of using a DELL PC
Now, THAT is a VERY expensive PC, and DELL certainly will not see me again.
