One extra piece of advice I would add is to try and use the laptop (or a slightly different version of it) in a shop – PC World/Currys/etc. – if possible before you buy, just to see if the keyboard and screen are to your liking. You’ll be using these two things a lot and if they’re not right for you – maybe the keyboard doesn’t feel right, or maybe the screen isn’t good in direct sunlight – then that’s going to mar your experience of the product for a long time.
Anyway, I hope you will be pleased with your purchase, whichever you buy.
