EDIT: Kobo mini for $49 (black) at OfficeWorks and talked to David Jones; they'll price match it.
Kobo Mini Grey going for $59 dollars at bookworld with $5 evoucher redeemable ONLY on bookworld.
Angus & Robertson online also has the deal but doesn't include the ebook voucher.
Usually going for $99 (at JBHIFI and other retailers), Cheaper than Kindle's $69.
Note that the books are a bit more expensive on the Kobo than the Kindle but Kobo allows e-pub books.
got one of these in the previous JB deal ($49) and love it!

it's an awesome little unit…not as full featured as other ebook readers (a bit slow, older e-ink technology, no backlight, etc), but it's super portable! the tradeoff is definitely worth it for me…it fits in most pockets, ie. pants (but just slightly too big for my shirt pockets).
highly recommended if you value the extra portability! (particularly if you can get it for $49)
