Acer Launching Android 3.0 Tablets in 5, 7, and 10-inch Form Factors

Acer appears to readying Android-powered tablets in 5-inch, 7-inch, and 10-inch screen sizes. The 5-inch version is aimed at the same niche area as the Dell Streak. The largest version obviously will compete with the iPad.

The interesting developments to watch are how popular each of the form factors turns out to be. To the extent that a tablet is primarily a content consumption device, the issue then becomes which form factor is deemed most useful.

Personally, I find the 10-inch form factor unwieldy, for that purpose. On the other hand, a 4.5-inch screen often strikes me as a bit too small, though that isn't the only consideration.

Overall size, weight and battery life are important considerations as well. At the moment, I'd say the big issues are battery life and size. About seven inches seems to me the best compromise between extended battery life and screen size. Any bigger and I don't want to carry it routinely. Any smaller and I'll just use my Evo.

Acer to Market Tablet and E-Reader

Acer Inc. will start selling its first e-reader later this summer and also a touchscreen tablet computer in September or October, according to the Wall Street Journal. The e-book reader features a six-inch display, while the tablet PC will feature a seven-inch screen, and is powered by Android.

The interesting angle here is that consumers will have a choice of form factors. Apple's iPad uses a screen that is almost 10 inches diagonally, while Dell will sell a device with a five-inch screen. Acer is in the middle with a seven-inch screen on its tablet.

The issue, beyond the broad issue of whether tablet PCs represent a new PC segment or a new device category, partly hinges on what people decide they want to do with such devices.

Smaller screen devices such as the Dell might be seen as functionally similar to smartphones, in terms of portability. Large-screen devices cannot be conveniently carried in pockets or purses, and likely will compete more with netbooks or notebooks.

The Acer e-reader, dubbed "LumiRead," has a six-inch display and is equipped with two-gigabytes of flash memory, which allow it to store up to 1,500 books. Acer, which shipped more PCs than any company except Hewlett-Packard Co. in the first quarter, will sell its e-reader first in the U.S., China and Germany.

Apple iPad Ignites War Over Market That Might Not Exist

With rumors that Google, Nokia, Hewlett-Packard, HTC, Acer, Dell, Lenovo all are working on tablet devices in the same class as the Apple iPad, I suppose it has to be said that those companies do not want to take a chance on Apple having discovered a new mobile device category, and not moving early enough to participate in the segment's growth.

It's just that nobody has yet proven what the market is, or how big it might be. But nobody seems to want to take a chance that a market exists, and that Apple will stake out leadership before anybody else can mount a challenge.

That is not to discount Microsoft's historic interest in the tablet segment of the market, but simply to point out that, up to this point, the segment has not gotten much traction, perhaps because "different interfaces to the same functions" has not resonated. Microsoft's approach has been to envision a PC with a tablet design.

Apple's approach is more similar to that of the Kindle and iPad "touch," though, more a media reader and entertainment-driven Web appliance than a 'notebook with a different interface.'

The range of rumored interface, operating system and featured applications illustrates what happens when suppliers try to position a new device mid-way between smartphones and netbooks and notebooks.

Hewlett-Packard is said to be debutting a slate computer that it will offer by midyear. H.P.'s slate will have a camera and ports for add-on devices, like a mouse.  Apple's iPad appears to dispense with those options.

Under the hood, the iPad is powered by what might be called a "smartphone" processor, while others likely will try to use "netbook" processors.

Google might try to power its slate using Android software, which was originally designed for mobile phones.  Those hardware and software choices show some of the issues involved when trying to create a new class of devices mid-way between netbooks and smartphones.

Then there is the matter of "niche" to pursue. Apparently the first the idea was to create a device for designers and architects, but lately the company is thinking of a broader market of consumers and so would include e-books, magazines and other media content on the device.

Nokia is said to be designing an e-reader. The point is that there is so far no clear consensus about what the category is, how people will use the devices, or whether there is only one large, or multiple more specialized categories, to be satisfied. That accounts for the diverse choices about featured applications, processors and operating systems, among other choices.

All for a market that nobody knows exists, for sure.
