Tablets with larger screens due?

At a recent Amazon press event, I learned that tablets with big displays are going to be released by hardware manufacturers, which could ultimately supplant all-in-one touchscreen PCs.

The information is based on manufacturer product showcases witnessed by an Amazon product manager involved with tablets and ultrabooks, who said that the companies involved will feature these devices in upcoming ranges, due this year in either Q3 or Q4 from Amazon.co.uk.

I asked if these will be in the realm of the big all-in-one displays, like current 22in touchscreen computers, but the Amazon employee said they would be smaller than that, describing them as being much larger screen-based tablets than we have currently seen.

Amazon.co.uk currently retails all-in-one products from company's such as Lenovo, HP, Dell, Acer and Asus. It is likely that one or more of these hardware vendors will produce these larger tablets.

This is a logical, if not a natural progression for these types of devices. Tablet processors are becoming more powerful - take the quad-core 1.3GHz Nvidia Tegra 3 CPU inside the Nexus 7 for instance, so with even more powerful CPUs they have the potential to take a share of the desktop computer space - think Microsoft Surface or Samsung Slate PC.

Graphics power is on the up too. The Tegra 3 is also backed by a 12-core GeForce GPU, delivering performance that can rival that of previous gen integrated graphics. This is also supported by a dedicated Nvidia channel in the Google Play app store, with games written specifically for that chipset.

One should also not forget that the current spate of all-in-one computers tend to have a larger footprint than that of a tablet, so the incentive to move toward a smaller and thinner form factor while still offering a large screen size and resolution is definitely an attractive proposition. For example, the Asus 15.6in screen-based ET1611PUT all-in-one is 4.3cm thick and the Asus 10.1in Transformer Pad TF300T tablet is a smidgen under 1cm thin.

I'd not be surprised to see Asus making these devices, although we've already seen Japan-based company, Kouziro, showcase a 21.5in tablet.

HP has a good lineage in all-in-one devices, too, and coupled with its established history of producing touchscreen products - like the Pavilion, Compaq series and more recently its TouchPad - it's probably also prime candidate for entering this market.

I have contacted the various companies that currently make all-in-one computers to find out more about these big tablets, but I have a feeling I won't be getting any firm answers until Berlin's IFA consumer technology event in September.
