The ViewSonic VSD241 is an all in one PC which runs Android 4.1 Jelly Bean. The device features a 24 inch multi-touch IPS panel, MHL connectivity and is powered by an NVidia quad-core processor.
It may not be in par in performance with a full fledged all-in-one PCs but would be good enough to get you through most basic tasks.
We felt this device would greatly benefit from the Android 4.2 Jelly Bean update, which comes with multi-user support. We also suspect that manufacturers exploring larger form factors could indicate a merging of the Chrome OS desktop system with Android sometime in the operating system’s future.
Like most all-in-one devices the VSD241 comes with a keyboard and mouse, which may feel a little out of place for the touch optimized Android. While it may not replace the functionality of a traditional Windows, Mac or Linux computer it should be ideal for general users in this post PC era.
