My workplace just bought some 15.6" Vostro laptops. They're pretty well built for their price point. The BIOS menus are very well thought out. Only 2 screws to open the maintenance cover: RAM, HDD, wireless card and CMOS battery are easily accessible, CPU fan not so much though. Matte screen. AC adapter is really small in size. Keyboard is a rather usable chiclet one with numpad, but it lacks a Pause key. Also missing is HDMI output.
Runs cool, but no dedicated graphics card means no demanding games/3D design stuff.
These came with Win8.1 preinstalled and too many partitions on the drive for my taste (one for UEFI, three for Windows, and three more for Dell recovery/diagnostics/factory image). I removed most of them on mine, but I'll write that within a "more" tag so as not to clutter this thread.

First thing I did on mine was run built-in diagnostics to check all was working out of the box. Then boot preinstalled Win8 to create recovery DVDs using the Dell utility (which thoughtfully puts drivers and software on a separate DVD). With these I no longer need the recovery and factory image partitions. Then boot a live Linux distro to backup the diagnostics partition (hidden 40MB primary FAT32 labeled DIAGS). Then repartitioned the whole drive. Disabled "secure" boot and enabled legacy boot options in BIOS, put Win8.1 on a single primary partition just in case, restored the DIAGS partition to another, and Debian (soon to be upgraded to Devuan because systemd sucks) root/swap/home on an extended partition.
