Why have Apple kicked you?
The iPhone is more than just a touch phone.
I have used both Windows and OSX and I had no end of trouble with Windows, and everytime I visit with a friend who has Windows, they have [Poor language removed] loads of apps they don't need which drains the memory. They are chock full of adaware, they need to defrag every month.
The reasons why iMac's are more expensive, and I wouldn't say £800 is expensive for a computer, is because they are better made.
I'm not some Apple evangelist, but I have used both and have based my opinions on my experiences. Apple is used in government buildings, movie production, sports science installations, designers, etc.... The reason? They are robust and easy to use. Ironically, people who want an easy machine to use tend to pick a PC and Windows, which is the reason why viruses spread, and I get called by most of my family asking me to fix their sodding computer.
I just say get an Apple, I will give you a quick ten minute whistle tour and you will be set for the next two years.
