Ive decided to keep my troublesome Glo HD on life support (charging every 3-4 days) until we see a new Kobo, there should be one along in the next few weeks judging by the historic release dates on Wiki:

Worst comes to worst Ill just splash out on a Forma, the more Youtube reviews I watch the more I like it but it is very plastic for the money and I dont like the pattern of the rubber on the back but if the next Kobo isnt great Ill go for it, Ive pretty much ruled out all other brands in the last week or two of research.
Actually I might just chance buying another Glo HD on Ebay and hope the battery is still good if the next Kobo doesnt live up to expectations...
