MacBook Airs as Low as $649 With Best Buy EDU Deals

I do find it very unfair when a product is constantly cheaper in another country by a long shot (this deal works out to £440!). I gives the impression that not everyone is equal and Apple feel that the US is better that everyone else.

Nope, many factors affect pricing in other countries.

Economies of scale (larger customer base in US vs UK).
Shipping costs.
VAT.
Sales tax (in the US, sales tax isn't figured into the advertised price).
Currency conversion (Dollar vs pound vs euro, etc., varies daily, but Apple's price does not. So Apple has to charge a price that considers the fact that the value of the local currency will vary day by day, along with profit).
Local supply and demand (if you're willing to pay for it, they can charge for it).
Cost of advertising in local country.
Warranty requirements (consumer laws in the EU require warranty rights not required in the US, making European products more expensive).
Labor laws (for example, Apple employees in Australia negotiated a 16% base pay increase; that increase may affect local product price).
Local competition (less competition means higher prices, as long as demand remains high).
Legal fees (Each country has different roadblocks when it comes to doing business there. As a foreign company, Apple has to negotiate national and local requirements in terms of establishing itself as a business. In Europe, Apple has to deal with both local and national laws, as well as the EU).

4 GB? :eek: No deal. Even 8 GB is too small these days!

No.

RAM is not upgradable on these machines. A buyer will be stuck with 4 GB. There is speculation that Yosemite may not perform well on only 4 GB.

dude, no there's not? Yosemite performs excellently on a mid-2010 white macbook with 4gb...

if only they carried 8gb models.

It runs on machines with 2 gigs of RAM, so pretty sure 4 is fine.
