I've had my XPS M1330 for over 2 years and it works good as new! I've had 2 laptops before this but I've had to get them replaced within a year or so.
I have the core 2 duo processor and 4 gb of ram, which makes it very very fast! its perfect for daily use and for gaming.
The best thing about this laptop are the funky little features it has, mine has a fingerprint scanner, it also comes with a media remote which slots into the side, very very handy if you're playing a slideshow on the laptop or if you're watching something and you're feeling a bit lazy like I tend to and want to control the volume or rewind/ forward something. I also love the touch media buttons and the funky cd rom drive! Judging on the time I bought my laptop, the features on it are very advanced.
The mic and webcam on the laptop work great and are a nice little extra feature to have.
One of the best things about this laptop is that it is very very lightweight! Its small and compact, it can be carried in a handbag, which makes it great for me as I hate carrying laptop bags around. The chrome and black are a brilliant combination giving it a very sleek and stylish look.
The only cons about it would be the battery life, after a year my battery life seems to have dropped a fair amount, it lasts only 30-40 mins when it is off charge with wifi on which is problematic if you have no where to plug it in, though it works perfectly fine when plugged in.
Another issue is the charger, the adaptor on the laptop went bust in about a year and I had to reorder one from dell.
Also I find the xps range is marketed on the more expensive side. Though I believe it is because they tend to have excellent specifications, lots of quirky little extras and seem to be the more stylish looking ones.
This is a very reliable laptop and has all the functions you could need and a few extras in a personal laptop. It is built to a very high quality and value for the amount paid.
