Kobo eBook & eReader - Competition for Amazon Kindle?

So now for my 2nd blog comments...  I have a book I am reading for a 3rd time, yes, 3rd time (as it is that good) which I will give a review on tomorrow; hopefully to tempt you to look for; the only reason I am delaying it is because my Kindle ran out of power today, this morning in fact, so whilst at my sister's house this afternoon, I borrowed(!) her device which is a Kobo.  I must admit it was a new one on me, however, I liked it that much, I have brought it (kept it/nicked it/she keeps ringing me-oops!) home with me tonight and I just needed to let you all know about it.  Don't get me wrong, I love Kindle's and especially the one I own but I just needed to express my thoughts on how good this cool little Kobo thing is.  As you all will know there is some worthwhile competition out there, quite a few in fact, too many to write about and if truthful, I have only ever used a Kindle before today but this thing is brilliant, and the battery has not even gone down half way after using it for most of the afternoon as I knew my sister had the same book (the one I am reading a 3rd time-nearly finished it) I was reading on my Kindle with her having it on this Kobo.
