When it comes to Apple computers, I tend to never buy one just when they are released, from past experience they always have some issues etc.
I usually wait a couple of months for these to be ironed out. Apple will never acknowledge they have changed components in that time, but they work with the supplier to iron these out.
The current MBPr is very good, you probably will not see Haswell ones till late Q3-Q4 this year.
Given the usual Tick tock Intel jumps, your probably looking at 10-15% performance upgrade. If that matter for you wait. If it does not the current model is great, get a Samsung screen one

At a COST! We're talking £270+
That's a lot of money on top of the £1800!
Look on ebay. You will find its alot cheaper. Have a search.
Also you do not have to buy Applecare here in the UK. You can buy it from anywhere around the world. The last 5 I have bought have been from the states, never had an issue, and soooo much cheaper. I have bought it overseas and had to code mailed to me within minutes.
If you look on ebay, always go with sellers with very high ratings. Thats the only advice I can give you.

It's not an offer. You get AppleCare for £40 as a student in the UK - at least, that's what I was offered last time I bought something.
was that one a notebook or another product?
