Believe me, even this good price is a bunch of money, having bad luck from the start is a good reason to stay away, especially when competition is huge. Had used many brands indeed and had an Inspiron in the past that survived for years, but wasn't impressed. With this new one, before it died I was disappointed by its weight and bulky form. It's weird how plastic feels, even if its made from metal. Touchpad is insensitive and buttons clicks, fan is very active when you do simplest tasks. If you have a dell, you want to hear good things about it, but for me, whilst hp, asus, lenovo and tens of brands are on the market, dell will be a no.
I'd argue you are probably the exception rather than the rule to be honest - much as I feel for you when a brand new piece of kit doesn't work right off the bat, I've owned a number of Dell laptops over the years and without exception they have been very reliable! This seems to be a very decent spec for the money - I would have liked 16GB of RAM and an SSD in place of the HDD but these are easily remedied! Main gripe is the 60Hz screen but you can't have everything at this price point!
I hope this deal helps some people, same as I hope that my comment will make up your mind too. Bought this from Dell, opened up, finished the setup, haven't installed any games or something, shut down over night, next day turned on the button, leds were flashing and fun were noising, but the display was death black for ever. Tried a couple of times over the day, packed back and sent it to Dell to get my precious money back. It may be an isolated case, but from now on I'll definitely choose another brand.
60Hz according to Currys.
