Hello, I'm a PC user and I'm in need of a new computer. I have recently decided to buy my first ever Mac. We decided on a desktop because I want to have a machine in a dedicated space (instead of using it to multi-task). Can you please help us decide if the 21 or 27 inch is better? I will use it for web browsing, basic document stuff, and learning photoshop elements. I thought the 21 would suffice for this. But I'm leaning towards the 27 because my partner is an attorney and occasionally works home from the weekends. It seems the 27 would allow them to work on 2 documents side by side. At work they have 3 monitors, so right now working at home on their laptop is a pain. The price difference between both is OK for us. Is this a good enough reason to get the 27? Will it be too big for all other tasks? How far away do I need to be sitting from the monitor to avoid eye strain with such a big screen? I'm trying to figure out if our desk is even big enough or if I need to get something with a keyboard tray. The roundup on iMacs says to wait to buy one but I can't tell from all these rumor websites if there is actually something new coming soon, and if a newbie user like myself would even be able to notic any "new features". Last question - thoughts on the Magic Trackpad? At the store it seems like my finger would end up hurting from the pointing but maybe I'm not used to it. Thanks all!
