Nice link on 3Q2010 Ereader market share.
Note: The link ignores the IPad and Smartphones and only talks dedicated e-readers.
So some food for thought:
41.5% were Amazon Kindles with
16.1% were Pandigital (Who?!?)
16.5% were the Nook (Barnes and Noble)
8.4% were the Sony Ereader
8.2% were the Havon Wisereader (who? Apparently sold in China)
Now this is prior to the Nook Color. So I expect B&N is solidly up at #2 despite the low international presence (this is a global market share, not US market share).
I personally chuckle at the 15 million ereader sales predicted in 2011. It will be higher (despite tablets and the popularity).
Yet from that time Amazon had 76% ebook market share in the US.
So this implies:
1. Amazon is losing out in some international markets (China is certainly going to be a weak point.)
2. Applications are almost certainly a substantial part of the ebook market (no duh...)
#2 is important. I personally think that if ebooks in one form are not available on a preponderance of devices, that format will find 'growth resistance.' e.g., where is the iBookstore app for the PC?
I wish the data didn't have such a huge time lag...
