This just in, emphasis mine. I still find it odd there's no indication of Kindle per se:
Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_3; en-us; Silk
/1.1.0-84) AppleWebKit/533.16 (KHTML, like Gecko) Version/5.0 Safari/533.16 Silk-Accelerated=true
Really Big FYI
: Silk hit html files, graphics, and favicon from amazonaws.com AND, seconds later, from Comcast:
AWS Silk = 403 because of AWS [webmasterworld.com
...] independent of AWS-cached acceleration... Or non-acceleration: One of many such reports: [foxnews.com
Comcast Silk = 200. No clue what the latter actually 'saw' because ironically, the files viewed were highly formatted to mimic hard copy and would lose a LOT in any translation.
