There's a reason why this unit gets great customer reviews. It's always nice when something exceeds one's expectations. I bought a Samsung laptop a year ago with and i7 on board with the same specs of solid state drive and 8th gigs of memory. This device with the i5 blows the lid off my $1,200 laptop. With the power transformer in the cord there is no power fan in the unit, only the one for the processor. Mine was making annoying droning sounds so a teck came out and replaced it for free the next day. Dell support is awesome! Unfortunately that didn't fix anything. I had positioned the unit standing vertically but realized there were no feet to be in that position. So I moved it onto its side and haven't heard a peep out of it since. This is a great machine for the money and you get unparalleled Dell support to boot. In a word, buy it!
