I suspect the non-Kindle Fire/non-Nook part of the Android tablet market share is a rounding error. Also see Ha! Your “Limited Function” Kindle Fire Is No Match for My Magical iPad! (AllThingsD) for related Tim Cook commentary.
Apple’s iPad reigns supreme from whatever angle you choose to look at the tablet market (profits, apps, quality, market share, mindshare, you name it), but research firm Strategy Analytics this morning said Android did manage to capture a record 39 percent tablet OS market share in the fourth quarter of 2011.
Apple maintains the lead with 58 percent market share in Q4 2011.
