Thank you for the mention, montsnmags, and you're right, I am certainly an ebook enthusiastist. I've been reading Mobipocket ebooks for many years on my mobile phone. Now, I prefer to use my iLiad - the large screen size and e-Ink give a much more comfy read.
SubElement, the only Sony PRS I've seen is epiphany's and I thought it looked very stylish. I think the biggest concern with Sonys in Australia is that you purchase them with no warranty. The Cybook is also an elegant device.
If you're in Sydney, you can see a Cybook and iLiad in action at Dymocks. If you're in Melbourne, you can have a demo of Cybook, HanLin V3 and the complete iRex range at DA Direct.
My recommendation, if you're wanting a 6" device, is to look at the Cybook and HanLin V3 (or clone). If you purchase locally, you get Australian helpdesk support and warranty.
DA Direct is a long-standing Australian owned company, located in Melbourne.
And... epiphany, I think we should get together and organise an MR Melbourne meet. I'll send you an email when I'm back on deck at work. I've met several MR members already and I think it'd be lots of fun for us to get together for a show and tell.
