Apple has a lot of rumored revamps coming up, including new MacBook Airs, new Apple TVs, and even new LED Cinema Displays. This could mean a lot of the older models will start to be discounted, which could be partly why Amazon UK has just dropped pricing across the board for almost all of their Apple products.
As of this writing, a search for Apple products on Amazon UK reveals many Apple products with prices cut back, even if only by a few British pounds. Considering the exchange rate, however, that translates to quite a bit more in savings when it comes to US dollars.
Unfortunately, a similar search on the US Amazon store doesn't show quite the same savings. Several items do have the prices reduced but not by nearly as much. This is an interesting development since Apple recently raised app prices in the UK.
