Well I plumped for the EEEBox B202 and overall I’m quite happy with it.
Seems to render streamed Divx movies quite happily received over an 802.11G wireless link.

One problem I do have with it is the lack of MPEG2 Hardware decoder in the graphics chipset.
I have a Hauppauge WinTV Nova T USB2 DVB-T receiver for receiving broadcasts here in the UK and have had to find a softare MPEG2 CODEC to decode the received broadcasts. It seems the chipset is not up to rendering stream very well (low frame rate) on my Bravia flatscreen.

I might have to wait for the higher specification EEEBox B204, B206 or B208 when they are released in the UK.
