In anticipation of Christmas (yes, I know it's 6 months away, but recreational expenditure has to be carefully planed in the B household), MrsB has suggested she get me an ebook reader so I can carry enough reading material for working away without giving airport luggage scales a hernia. Based on some quick internet research I'm leaning towards a Kogan, 'cos it's cheapish, appears to do everything I want and has had a few positive reviews. However, I thought I'd throw it out to the collective wisdom of Netrider to see if anyone has any particular recommendations or, perhaps more importantly, any tips on what to avoid. I'm looking for something decently compact, robust, with decent battery life and the ability to read a wide range of file formats. No being locked into a proprietary system for me . Otherwise, I'm not fussed. Style, branding and a zillion features I'll never use are irrelevant to me. Thanks in advance.
