Well, having been pointed in the right direction by Charlie I decided to buy a dual core 1.6 GHz CPU + quad core Mali GPU android 4.1 on a stick: http://www.amazon.co.uk/gp/product/B008 ... UTF8&psc=1 which although not stated on the details came with power pack and USB lead included.
This is the specification:
The Jellybean OS is a sort of Hybridised version optimised specifically for use as an HDMI device using a 2.4 GHz remote keyboard/mouse combo
There is an additional icon along the bottom of the screen which allows for 2 viewing modes, as either TV mode as shows in the picture above or the usual android mode where all the icons revert to the stock android ones.
This is what the device looks like inside although this picture is of the earlier model I don't believe the hardware has changed , just the case:
My first impressions upon un-boxing is that the box shouts quality over and above what the device deserves although it does appear quite sturdy apart from the flip up aerial - as with many electronic devices it comes in a box many many times larger that the contents.
I had previously obtained an HDMI extension lead from Amazon: http://www.amazon.co.uk/gp/product/B004 ... UTF8&psc=1
to allow me more chance to hide the device behind the TV and using the supplied power supply and lead I was soon connected up to the kitchen TV.
I was disappointed with the WIFI reception as my WIFI which supplies the kitchen via a repeater/extender was shown as out of range on the device even though all my other devices (laptop and tablet) connect and work OK - however my next door neighbour's WIFI seemed quite strong so I moved to the lounge as I have got things set up so that with the dongle behind the TV it will only be about 3 feet away from my router.
This proved to be effective and solved the WIFI issues but does emphasise that in order to work trouble free you do need a good strong WIFI signal available to the area where you want to use the device. This could be why a WIFI analyser app is pre-installed:
Those of you who have followed my exploits so far with the raspberry Pi will know that my prime reason for wanting a device like the RPi or this dongle is purely to stream my movie collection from a NAS drive to my TV. The RPi did the job but not as fluidly as I liked so I am very pleased to report that even though the RPi was directly connected via ethernet and this dongle is connected by WIFI, XBMC absolutely blazes along
This pic is not from my system and is only for illustration.
So far I can thoroughly recommend this device for the purposes for which I want it which is purely the full and fast use of XBMC.
I shall be interested to see Charlie's review on his device as we both have differing reasons for purchase.
My device is not rooted but I don't need it to be.
I shall keep my stock OS as it is optimised for my purposes whereas I believe Charlie can now change his if he wishes.
In both cases, you can turn your TV into a fully internet connected android Jellybean based smart TV for less than £50.00.
One advantage over the RPi is that I don't need to purchase separate codecs to play Windows based files or MPEG2.
