Personally I would look at your budget and plan to that, look at the features of everything in your range and make sure you get what you need and don't pay for extras that you don't need. And remember, a Windows based laptop will be much much easier to add a bigger hard drive or more ram at a later date if you need it, with a macbook you have to make that decision now and pay for it now. There is no going back and adding an extra 4gb ram later.
I switched from Windows to an Apple MacBook for my home computing about 5 years ago. My initial concerns about having to learn a new operating system were completely unfounded. I still have to use Windows at work and it really highlights how superior Apple is on almost every front.
Don't buy laptop. Windows 8 is awful. If you have an iPad you will regret it. I have had a samsung laptop with i5 processor for last year and am about to throw it out of window. MacBook Air is more expensive but is what I am going to get.
i've owned a mac for about 4 years now, i managed to pick up a late 2008 13" macbook for about £700 on eBay (was only 8 months old at the time and barely used) - upgrading the parts wasn't cheap (new RAM sticks and new HD) but the very model is still going ok; the screen is fecked (i think the screen needs replacing) but i've not decided whether to a) replace it and drop 400+ for it or b) hold out and save for a brand new one.
Anyway, it's a solid choice to make if you choose to - i did it for work but you may decide that you prefer to stay with a Windows laptop, it it's only 'general' things you'll be doing on there.
I'd recommend trying a mac first, just to see if you get on with them. I love them, but Mrs Grombleton hates them.
Have you thought about buying a 'Not Working / Spares Repair' macbook from ebay and trying the replacement yourself?

It sounds a ball ache, but take your time, and get the right tools, and it's actually not too difficult. You might end up replacing the display for about £70.
You know what? I think i might love you. I'll def give that a go!
