The machine is actually a model 9010, which should be a good thing. However:1) Physically, there is an open slot on the back just below the accessory connections, above the power supply.  I assume this can let in dust and other dirt, as well as disrupt the cooling flow inside the machine.2) There is a dongle in a USB slot, with a flashing blue light, labeled "COMFRST".  I have no idea what this is.3) There are USB slots labeled with the traditional "trident" symbol, then there are slots with the "trident" symbol preceded by the characters "SS".  I assume there's a difference, but I don't know what it would be.4) There is no user information included, such as a user manual, a "Quick Start" card, or anything of the kind.  It would really help to have a user manual to figure out the differences between this machine and my old (dead!) Gateway 5637E.5) There is no information on the Windows 10 Desktop software.  This is a problem for those of us who are/were still using Windows Vista and the Microsoft Desktop packages (Office, etc.).6) I have still not figured out how to transfer files & documents from my old (dead!) machine to this one.  That's causing problems with the use of my peripherals.  E.G., I can't get my Epson flatbed scanner to work because it has no drivers.  When I attempt to download drivers for it, I end up on the Dell driversupport site which wants to charge me major fees to download the drivers.In short, it would have helped a whole lot to have some user information, such as a user manual, included with the computer.  After all, there are actually still some of us dinosaurs around who are not familiar with Dell equipment or Windows 10
