Want another large monitor, an LED tv/monitor on the wall. Wife is planning on having a built-in desk/cabinet/shelf so I'm unsure of what will happen to "my" office. She is also adding lounge chairs. If I have lounge chairs I may put up a tv/monitor in addition to a 2nd monitor. I have a Macbook Pro if I really have a need for another screen.
Windows used primarily on my iMAC, hah. I'll probably purchase a PC in the future. Mac products are used because they are kid/family friendly and the products streamline across our devices with hardly any effort. Syncing will be performed and backed ups will be stored away from my computer in a central location/harddrive. The setup provides the necessary equipment to produce profits. Everything else I'm planning on are extras. I have a PC desktop that I left at my previous house. It was a higher end model 8 years ago and is still probably of use today. If nothing else, I can update it.
I have this grand idea to hook up a computer to the projector in my home theatre that is in development. Not sure how it would function in the practical sense.
Works fine but don't assume you're going to have 9 screens worth of space. Look at the resolution on the projector and that's how much screen you'll have to work with.
