OK, so background info, may or may not be useful. I currently own a 2011 17" 8gb ram / 750gb 2.2 GHz quad, Radeon HD 6750M 1024 MB. I broke the screen..bad. Replacing the screen would be crazy expensive, selling a busted mac will get me nothing so I have been using it with an external monitor, keyboard, trackpad, and 2 external drives (5tb combined) not counting the 3tb between two time capsules. I would like to get another machine I can grow with, if I hadn't broken the 17" I would most likely just be upgrading the ram and HDD but I like having one docked so someday the new one may be docked, replacing the 17", and I'll get whatever ultra compact laptop comes out at the time, years from now. I seem to use a lot of hdd space so the limited amount available on the new machines was a problem... until I decided to keep the old one. I'm thinking I will use the old one for the big data hogs like syncing all of those iOS devices, photo library, and downloaded videos. With all of those gone I shouldn't need much space on the new one?? Anyone run into issues trying to compartmentalize info in that way? Do you find things like iCloud, Dropbox, and google drive are sufficient to run multiple macs (I use all three). Would buying the remote desktop from Apple be worth it with just 2 machines or do you think TeamViewer is enough? What to buy?? I think I'm pretty much set on this unless you think I'm just flushing money down the drain. I'm sure Apple planned it this way but at first I looked at referbs but the FT trackpad is kinda awesome and the new SSD is so fast.. 13" looked good but kick it up to 16gb and it is almost the same price as the 15" quad core.... then (with the student discount) it is only a few hundred more to get a much nicer graphics card and the ssd is not just larger but faster.. a lot faster, something about the 256gb basically being 2 smaller ones and the 512 being a single unit? The graphics card could come in handy if I do use this thing as a docked machine later.... Am I crazy or is this reasonable if I can afford it? Lastly, does anyone know of any articles that give tips on running 2 machines, things like sharing photo stream but occasionally moving older ones to the backup drives to save space, being able to remote access external drives. Am I missing anything? Thanks everyone!!
