You should borrow your daughter’s computer to edit at home too! 🙂
I have the same 2012 iMac for my home editing. It’s probably been 3 years since I edited a project with anything but X. Flanders LM series monitor for video. BMD ultra studio or t-tap for sdi out to the flanders. A second Dell 22″ monitor for the event browser. Pegasus 4 raid. Variety of other usb 3 drives / raids for backup and such. Old MA-12 speakers that used to belong to an avid suite in the 90s for speakers.
My wife’s laptop must be our home computer because as far as the IRS is concerned the iMac is for business only. 🙂
Some weeks/months I’m editing 10-12 hours a day stopping only to pick up kids at school or the bus stop. Often they’re right there next to me on my old 2006 Mac Pro 1,1playing angry birds or watching something horrible on YouTube.
I don’t edit on the road, but we have a 2012 MacBook Pro that still runs X pretty well even if it is an i5. I can always rely on that as an emergency backup or to edit on a shoot if need be.
I’m looking for a laptop and a new iMac in the next 6-12 months.
