Hi I decided to switch mac beacuse I realised doing simple things on windows is a pain. But I am not sure which Mac to buy. Macbook's portability is a great advantage but it's screen is small and it's specs are low. iMac has much better specs but it's screen is bad and it's not portable. I will use my mac for at least 5 years. So which mac to buy. Please vote. Sorry for my bad english.
