Thinking about getting the i7/16gb/256gb ssd model. I recently got into photography as a hobby and started editing big raw files in lightroom. They're about 40mb+ each file and my current i7 laptop from 3 yrs ago is slow and lagging behind. I want the 16gb model because i might get into video editing since the camera does support high resolution video recording. Also I think 256gb ssd would be decent to hold files. If i need more space, i'll throw in a 128gb micro sd card into the slot, or run a usb3 external hard drive. what do you guys think in regards to upgrading to the i7 model?
