I'm with them, if it's a choice between win8 & 10, go for 10. Sorry for the miscommunication on that one!
If you can get win7 (won't get that on a new one) - well, that's more stable and you can simply disable the auto-updates, they aren't pushed on you.
I've had a dell laptop before and I was disappointed. I gave it away after a couple of years. The samsung was (is) superior in every way; looks, size, weight, battery, performance - you name it. But it could be that I've bought the wrong dell
Sadly not available anymore.
But what's worse - as I said - last we've had to look for a laptop for colleagues, we could not find anything that could stand up to this samsung one (for prolonged office use).
Edit: wrt win10 many people will loudly declare that it's perfectly good. But if you read around on the net, there are just too many people who have less than optimal experiences with it - essentially an auto-update breaks their laptop. This is what happened to us. Many lost work hours - luckily it somehow has righted itself by the next day. So keep a backup of your work off the lappy in any case.
