Hello everyone , I am in the need of a desktop computer,something that's reliable and always there when I need it. So I decided to go for the iMac,I haven't purchased it yet,its a bit pricey but I have the money,but I am not impatient,and I don't want to rush on buying it. So I have a few questions for you Mac users,Because I have never bought a Mac before. 1- Is it worth the huge price tag? 2- What kind of troubles will a first time Mac user encounter ? 3- Will Windows 7 cause any trouble when its installed via Bootcamp? and how many Gigabytes does Windows 7 need ? 4- How long does this type of Mac last ? Thank you for your contribution,I will be even more thankful if you give me some tips and advice.
