Now a couple of weeks and a couple hundred megabytes added to my device, much of which comes from the amazon store search string "free," I am starting to form an impression of what reads with more bother, and what reads with less bother than does the ink-on-paper method.
<> BETTER FLOW on Kindle than paper & ink; emotional satisfaction or creature comfort
-GET. It is easy to browse and receive published content, whether paid or free.
-READ. It is easy to set the letter size, turn pages, add bookmarks, notes to the text.
-SEARCH. It is easy to seek key phrases or passages, then bookmark or add to clippings.
-USE Text. Once tethered to computer, the clippings.txt file is easy to work with. And while your changes will go into this textfile, Kindle keeps the kindle-made changes out of view from the computer so that any inadvertent deletions won't affect the onboard ability to review bookmarks and so on. Ways to use the clippings file from the computer: elaborate on brief notes first created on the Kindle thumb-keyboard, email or blogpost extracts.
<> MORE FRICTION on Kindle; emotional resistance or tedious steps required
-Too many steps from Kindle to Kindle; to mobile device; to computer (beside USB cabled). All of these communications are possible by way of an intermediary computer, but it would be more enjoyable to form a temporary wifi connection to a neighbor's Kindle or computer to share content, or at least the clippings.txt file. Alternatively, as part of the kindle management website, perhaps a setting to "share my clippings file" would be possible to mark "public" or semi-public to those of one's choosing. That way any notes or highlighting could be seen directly by others from one's device in real time. Furthermore, being able to select multiple lines (instead of cursoring the highlight cursor one line per click) would be useful for readers who interact heavily with texts.
