I like many others on here am anxiously awaiting the update to the iMac. Unlike many others, I am sitting on a 2006 iMac that has served me very very well and been a great computer. My issues seem to recently be just minor bugs appearing and the constant beach balling opening applications etc. Just seems like the computer is getting older and more tired. Little things like hot corners are buggy at best and I often find strange things happening, like my Safari browser all of a sudden deciding that I need to open ALL of my Finance bookmark folder etc etc. Anyway, I work from home and use my iMac a ton every day. It is an integral part of my business and I fear there might be a time in my future when it goes to sleep and never wakes up again. That said, I want to be prepared. I don't want a PC, I am not technical enough to do a Hackintosh and wouldn't want to pay top $ for a 18 month old iMac. Would I be able to make do with a top of the line macbook and a great display? I am not exactly a power user, but do run my workday with a ton of productivity apps open and constantly move between calendar, email, numbers etc etc. I do like to do quite a bit of home movie editing and found that my iMac can't even handle my current HD footage anymore. Is there a high quality display that I could connect a Macbook to and retain Retina display? Do I need to worry about heat issues if I keep the macbook closed all day? Does it have enough power to be a true home office computer. Sorry if too long and rambling and unclear, I am just trying to sort out my options. Thanks!
