I bought this exact model (7537) recently as I want to replace my 5yo Samsung laptop that had seen me through Uni.
Really like it so far, bit of a hefty thing but I don't mind it really. The main criteria I wanted it for was at least an Haswell i5, 8GB and 1080p display. Only downside (or upside) was that to get the 8GB RAM & the 1080p display I had to pick the i7 option. There still doesn't seem to be many laptops out there that will do it at the price I wanted. Every fricking laptop seems to be perennially stuck with that stupid 1366x768 resolution. My 5yo laptop already had 1280x800!
Plus after having checked the Owners Manual on Dell's site I found I can upgrade the HDD to an SSD at a later stage. Can't really do that on most Ultrabook-style laptops unless you pick it at time of purchase.
Only downsides for me personally is that the track pad can be a bit stupid and not always picking up or registering 2-finger scrolls and the Intel Wi-Fi on-board can be a bit hesitant at times to connect to Wi-Fi even though it looks like it has done. Still having to get used to the keyboard being shifted to the left due to the extra number pad which I didn't have on my previous one.
Otherwise it's a smashing bit of kit for the price and will easily last me another 3-5 years I plan on keeping it.
