Tablets succeed across the board

Everyone has remarked on the success of the iPad. Now we have (slightly credible) evidence of other product success, and with that optimistic predictions for 2011.

By all accounts, the iPad was a strong seller this Christmas season, but the official results won’t be available until Jan 18, when Apple releases earnings and sales for the quarter ended Dec. 26.

However, intrepid Fortune columnist Philip Elmer-DeWitt contacted 27 analysts for their estimated sales for this quarter, and got estimates ranging from 5.0 million to 7.5 million iPads sold. (The mean was 6.35 million). That’s on top of 7.5 million sold in the first two quarters (4.2 million of that in the quarter ending Sept. 25).

So Apple has sold at least 12.5 million of its $500-800 iPad, and maybe as many as 14 million. Meanwhile, Apple is preparing to announced the iPad 2 (although predictions vary wildly as to what that is.)

Apple is not the only game in town, but it’s still the market leader. According to Forbes, analyst Craig Ellis notes that with 69+ tablets for sale, Asian suppliers expect 40-60 million tablets sold 2011. He predicts 53.6 million (not 53.7?) sold, and 36.1 million (67.35%) of those to be iPads.

Update 3pm: Similar figures come from analyst Robert Cihra (via John Paczkowski): 54 million tablets in 2011, 36 million (67%) from Apple — up from 14 million in 2010.

Craig’s guessestimate on e-readers is 20 million in 2011, up from “around” 10 million this year. Forester puts the numbers at 11 million and 6.6 million respectively (but those might be US-only).

Such estimates are impossible to check since the category king, Amazon, is evasive and non-transparent when bragging about Kindle sales. Sure enough, this week, both Amazon and Barnes & Noble this week issued meaningless press releases that say their Kindle 3 and nookColor are its best-sellers ever.

A Bloomberg report claims internal leaks from Amazon place 2011 estimates at 8 million sold, vs. 2.4 million in 2010; most of the former are presumably the $139 Kindle 3 Wi-Fi. Analysts believe B&N sold about 2 million Nooks — most of those nookColor and most in the past 6 weeks.

One difficulty in comparing tablets to e-readers is that the Amazon and certainly the B&N sales are primarily in the US, while tablets are a worldwide phenomenon. Samsung’s hoping to sell 9 million tablets in 2011, and from its tepid US results, most of those are likely to be outside the US.

So by the numbers, it appears that 2011 will be the year of the tablet. Next week’s CES in Las Vegas will bring a flurry of Android tablets, as well as Microsoft’s latest effort to compete in the category.

Still, so far everyone expects the tablet category to remain dominated by Apple in 2011, even if its market share slips in the face of product proliferation by its rivals. Using Craig’s estimates, Apple still retains 2/3 of the combined tablet & ereader category, while Amazon would be limited to about 20% at a much lower price point. (The What-me-worry? folks at Amazon also noted that many iPad owners are also buying the Kindle.)

I predict Amazon will introduce black & white Kindle this summer at the magical $99 price point, but will it be enough? More importantly, will people continue to buy into its proprietary media format? Or will the entry of the Google eBook store — with files that can be read on everything but a Kindle — finally start to nudge the industry towards a more open format?

Personally, the most interesting question is leadership of the non-Apple tablet market. Perhaps the HP webOS tablet will catch on, but most likely the leader will be an Android tablet, such as the one I own — the nookColor.

The nookColor has already been hacked to run Android apps, including (as long predicted) even Amazon’s Kindle reader for Amazon. B&N promises to introduce its own Android download shop in Q1, presumably excluding Amazon products from the subset of apps provided. At its aggressive $250 price point, it seems to be the early leader among 7" Android tablets — at least in the US market.
