Researching Mac

I'm beginning a search for information about the Mac computers.

Discovered so far: Macs are more expensive, but they are capable of fantastic graphics. 

Additional information needed includes Mac sizes and types of laptop and desktop computers, large format printers, larger scanners, photo editing programs, organizing and storing systems and if there is a program similar to Microsoft Office Publisher for Mac.

Anyone reading this, please share your knowledge by leaving a comment or a link to your web site or blog.

I plan to write a summary of the information gathered here on this blog and if possible, on my Gather page.  Anything from other bloggers or web sites will be used only with permission and sources will be given credit.  Otherwise, the web site address will be given, instead of direct quotes.

Thank you in advance to anyone who will help me in this search.
