iMacs

The book I read to research this post was iMacs: Portable Genius 3rd edition by Guy Hart-Davis which is a very good book which I borrowed from the library. This book mostly looks at OSX Lion the operating system for iMacs. Apparently the latest ones sport a 27 inch monitor. Apple has its own proprietary system for external hard drives called thunderbolt which typically runs at 1.5 GB/Sec. It's also compatible with firewire and USB 2.0 although they are slower. The operating system features a display of a desk onto which are icons of various apps or mini programs. Extra apps can be downloaded from the internet especially itunes. You can have a dual booting imac with Microsoft Windows as well. No one has found a way of making OSX work with a PC. Intel make the processors for imacs and most PCs. If you run an imac with windows it's much more resistant to viruses. Most viruses are specifically designed to infect a PC running windows because that's the most common type of computer. You can make video calls with facetime to things like iphones and ipads and mail is used for email. Many people set up accounts with mobileme and icloud which are free. If you use itunes one account is limited to 5 computers but a way around it if you have a bigger network is to make one of them computers a server which you can access from any computer on your network. Like windows you can have individual accounts for members of your family and if you download things like ebooks and music you can import them into each account so everyone has access.
