I don't see an excellent improvement but I do see some. I have a 4K TV and I thought by hooking up my computer to it I would be able to stream my youtube movies in 4K but it looks like a polished 1080p. +/- the video quality being streamed.
My computer is not only cool on the inside but on the outside, too. Made out of light but strong material.
Compact and powerful
I couldn't believe the small package I received in the mail was a compact and powerful external DVDE-R/CD-RW drive. It was so simple to connect -- just attach the cord to the back of the drive and to your computer. No extra power cord to get tangled up with all those other power cord. Small and compact, it has the same footprint of a CD jewel case. Mine fits on my desk and holds my lamp -- so sleek and small, it's almost a piece of my décor.
