On Google Editions, I don't see this doing that much for Android simply because you can't yet build a device that has both a good enough screen refresh rate to run apps and a screen that's comfortable to stare at for hours on end
Do you consider LCD-based screen techs like mirasol and Pixel Qi to be problematic in regards to comfort? I refuse to buy eink just because of the cost to utility ratio -- and frankly, because I like backlighting (I read at night every night, and frontlighting solutions suck). But for starters, I think viewing comfort claims about LCDs are overblown (I've been ereading avidly for 7 years; I've eread almost exclusively {sans some textbooks and a few nonfiction that stubbornly refuse to epublish} for 3 years, all on LCDs. It's all about turning the backlight down and avoiding the color white.), and with newer, better transreflective techs, I'm starting to warm to the idea of a good multimedia tablet that would serve as my primary at home reader (where I do most of my ereading anyway). One nice thing about the iPad is that mass market tech coverage has finally become convinced that LCDs can be used for reading. One might have realized this since most people read off LCDs 8 hours a day at work, but whatever.
Impossible to know if Google's own tablet will use something like Pixel Qi, but it would certainly be a nice way for them to set themselves apart from the iPad. Mass market journalists would probably hail it as revolutionary too, giving it an extra boost, even though it's already appearing in laptops and Notion Ink announced their Pixel Qi using tablet last year. It hasn't appeared in any really big name product yet.
how much of it actually concerned the iPad's use as a book reader? If you go to the Apple Store and watch people playing with iPads you're not going to see a lot of them reading books.
A ton of it. Apple has already succeeded in completely upending the way epublishing works. Amazon ruled things before, but since the iPad's announcement, Apple has managed to bolster publishers in such a way that everyone, including Amazon, has had to accept something called Agency Pricing, something largely credited to Jobs offering publishers a ealternative if Amazon decided to get rough, and giving Amazon a reason not to get rough). Now I run in a lot of ereading circles, so my perspective may be skewed a little, but there's no small amount of buzz regarding the iPad as a reading device.
And as I've said here a few times, market share numbers are a terrible way for us to make decisions
Indeed. But Android's momentum is an undeniable plus towards its support. Your RIM/Nokia arguments are fairly flawed, precisely because marketshare alone is a bad measurement. It should be marketshare of what? What's the install base of TOUCHSCREEN blackberries (I could be mistaken, apologies if so, but don't the vast majority of BBs not have touchscreens?). What's the Nokia install base of users for whom English is their native language? What's the install base of both who have
purchased at least one 3rd party application?
I love telling people, especially those new to the smartphone world, that Apple isn't the biggest smartphone player, or even second (jaws tend to drop). Who is? yes, that's right, those boring Nokias with virtually no US footprint, followed closely by those boring blackberries (no offense intended to BB or Maemo or Symbian users). And yet, when it comes to 3rd party application sales, Apple is indeed on top.
Android is often pitted against Apple while ignoring Symbian/maemo and RIM for good reason -- the two groups have very different niches they chase. Nokia could care less about backwards compatibility; frustrating users who want to make application investments and developers who want to make sales. RIM users have largely pigeon-holed the device for email, sometimes because their company doesn't want them doing personal stuff on it, and getting a second device for mobile computing fun. Android and Apple are different.
