Hi and welcome to MR fellow ozzie.
Keep on a-trawling through the forums in here and you should make a decision eventually. I did. I went for the Sony because I thought it would support all the formats I was interested in. And it was pretty.
Well you gotta admit if you spend as much time in bed with a reader as I do its gotta look good. You can't really close your eyes can you? (that is why the Kindle and iRiver were not seriously considered) Apologies to the Kindle and iRiver lovers out there, but beauty is in the eye of the beholder, and I did not behold that white beauty. anyhoo -
Go with something that will do what you want it to at a price you are prepared to pay. If you wait something better will always come along and you will be readerless in the meantime.
Good Luck
