You had a very niche device at the time that was far from the typical reader of 2010. 7 and 8" inch devices very much still exist. Kobo has the 7" Libra Colour and the 8" Sage. Amazon also moved the popular Paperwhite line from a 6" device to 7". Pocketbook has 7 and 8" readers. 7" only got MORE common if anything. Six inches was the most common eInk size for a long time. You can still get big format devices with notetaking. Now the big brands like Amazon and Kobo have them in addition to smaller players like Boox or Meebook.
