I currently have 2 Mac's - 2010 iMac Core i7 27" with SSD and HDD + DROBO - 2010 Macbook Air C2D All my documents sync via dropbox except for Media and iTunes/iPhoto libraries. I travel a lot. Does anyone have an opinion weather it is better to have 2 separate machines or would it be better to have only a monitor at home and plugin a portable when at home. I am not a gamer nor a huge media hound though I do have large iTunes and iPhoto libraries. I highly value SSD's. What are the pros and cons of having separate machines vs just a notebook with a display at home?
