I started the reader addiction in my family:
Me - Sony PRS-505 (2009) Kindle Keyboard 3G (2010) Kobo Vox (2011) Kindle Touch (2012) and my latest is Kobo Glo (as of last Friday).
Mum - 'joint custody' Sony PRS-505 (2009) Elonex (2009 - Now departed after youngest nephew played around with buttons too much) Imagin Reader (2009 backlit colour LCD reader) Kindle Keyboard Wifi (2010) and Kobo Touch (2011).
My sister-in-law has a Kindle Keyboard 3G one after my brother asked for suggestions for Xmas 2010. So my fault again!!
My Dad would love one but can only 'read' audio books due to being legally blind.
