£130 isnt for an operating system, its for an operating system and £70s worth of office suite
and nobody pays that anway, because its cheaper just to buy the £25 upgrade each time. Since when can you get an upgrade to the latest microsoft OS for £25 ??
Even the OEM copies are nearly 3 x that price.
And considering the RRP of Windows 7 Home premium full (what you get in the apple box set) is £149,99 without an office suit, the OSX software is very good value. Even accounting for the fact you can get a discount on that RRP and get it for more like £110, its still only £20 cheaper than OSX and with no office suite, and nothing like as good as Ilife09. Ilife 09s real time HD video editing is worth the £130 on its own, let alone the fact you get an OS and office suite with it.
There is hardly anything on the PC to touch imovie09, and windows movie maker is a childs toy in comparisson.
