its not just the machine, include the software cost as well
there is also the lifetime cost.. ie the amount you spend on the machine over time to keep it working
bearing in mind you are a student you can get student editions of software at knock down prices, you can also occasionally get student discounts (sometimes at the university your are at). Obviously you wouldn't want to copy soiftware form your mates.. would you (mind you you may be able to get hooky software for Macs these days as well)
You pay a heck of a premium for Apple Products, (sort of similar to Sony Vaios..) personally I dont think the price is worth it.
When you laptop goes wrong, and it will, then it will almost certainly be cheaper and easier to find a Windows Laptop repairer, you can probably find mates who can assist for free.. I donbt that you will find that many Mac helpers (there will be some... but potentially a lot fewer)
I dont believe the macs are easier to use hype.. they may have been years ago pre windows.. but no longer
So in the end its up to you...
Id happily consider buying a windows laptop from any iof the major players (eg HP, Dell, Toshiba or others). Id have a look at Acer, MSI, I'd also consider Lenovo (they took over making laptops form IBM)
Make sure your budget includes antivirus / firewall. I know the Apple promoters will claim you dont need AV for Apple.. dont believe it, viruses exist.
Personally if I were you Id spend nowhere near that amount and pocket the saving.. you can get a reasonable laptop for around £5..£600, if you want to spend more then consider gettign a larger screen and dual core processor, dedicatred video memory (NOT Shared). Alternatively put some of that saving into a decent laser printer. printing at Uni costs a bomb (get a reasonable quality B&W laser for around £50..£100.
Unless you have a specific need for an Apple, and probably that means a specific piece of Apple compatible software that you must use then Id steer well clear.
