I need to keep a large collection of images with me when traveling, since I never know which ones I need to pull up for client meetings or design reference. I also keep my laptops for about 3 or 4 years, so I want to allow space for future growth. I've had good experience with Lenovo X series. It seems all tablets use small SSD's, and I'm having trouble finding any ultralight laptops with over 500 GB hard drives. I can't depend on cloud storage, since that entails depending on reliable, fast cheap internet connections... those don't exist in many places. Carrying a separate removable drive undermines the whole point of a small ultralight. Note I also do a lot of photo editing/graphic design on the laptop, so I need lots of ram. Anything out there that fits the bill?
