E-readers have had somewhat hesitant popularity to date. There is a clear interest in the developing technology, but steep price tags ($399 for a Sony Reader, $489 for a Kindle DX) have meant that they haven't exactly taken off.
However, increasingly there is no shortage of supply. iRex recently released its iRex DR800SG ($399), where owners can buy books and newspapers using a global wireless network (Kindle users can currently only do so within North America) - and is planning to release a colour version by 2011.
With just over a million e-readers sold worldwide in 2008, improvements in the technology are expected to increase sales: market research firm iSuppli predicts that 5.2 million e-readers will be sold this year with a greater interest outside of North America.
So could e-readers secure the uncertain future of newspapers?
