According to this interview in the London Guardian, Neil Jones of Interead, claims that over a million Cool-ers have been sold worldwide:

Cool-er 'confident' it can beat Sony's e-reader sales in UK

wow, a million already ??? that's quite impressive !! and overall excellent news ; a million cool-ers sold means a million people reading ebooks ! looks like the ebook game is really heating up at last. now if only we could have some sales figures from sony and amazon...
"Surpassed seven figures", eh? Color me a bit skeptical. Maybe they misplaced a decimal or something. After all, how many Cool-er users do we have around here? I realize this place isn't exactly a representative sample, but you'd figure we'd have more than a handful if the Cool-er were actually selling that briskly.
wow but I thought the company that makes eink screens doesn't have the capacity to produce so many screens yet
I must say that I find this a bit hard to believe, and was wondering whether a million Hanlin/Jinke clones might be more accurate.
There can't be a million sold. Cooler has been on the market only a few months, and screen production during that time is measured (at most) in hundred of thousands. And that's screens for all the manufacturers (Sony Amazon, Jinke, Netronix).
hm, so is cool-er confused ? are they talking about ebooks (files) rather than liseuses ? an astounding backlog of orders they'll never be able to fill ? i'm surprised by the number as well but large numbers are totally abstract to me so i really can't tell how unrealistic this is.
They're a bunch of liars.
don't put the gloves on hadrien, tell us what you *really* think.
You have to admit he seems to have them sussed though Zelda :-)
