Viewsonic has quietly emerged as a decent producer of tablets with the ViewPad 10S coming out as a potent alternative to the iPad 2, especially as Zavvi has discounted it to a mere £215, almost half the price of the equivalent 3G-enabled Apple tablet.
Like the latter, it has a dual core processor, an Nvidia Tegra model based on the Cortex A9 chipset, 512MB RAM, 16GB storage (thanks to a microSD card slot and a bundle card), a 10-inch capacitive touchscreen (with a 1024x600 pixel resolution), Bluetooth, Wi-Fi, a front-facing camera (but no rear one) and full support for 1080p content.
Other features include 3G connectivity, mini HDMI, a microUSB port as well as much wider codec support compared to Apple's iPad 2.
Platformwise, the ViewPad 10S runs on Android 2.2 and is upgradable to Android 2.3 Gingerbread (but almost certainly will not get Ice Cream Sandwich).
Other less expensive options are the Hannspree Hannspad or the Advent Vega (although they are on a clearance list and therefore stocks are low) which can be had for around £150 without 3G functionality and come with roughly the same configuration.
