Color e-ink reader vs Flexible e-paper, which one to buy ?

In a few month there will be a released of these two technology into a ebook reader market, the question, as an ebook lover, which one to buy ? A color e-ink reader or flexible e-paper ? In my opinion, I am not so excited about color e-ink reader since I have seen it on Youtube, Hanvon color ebook reader seems interesting but with the pale colors, I don’t quite sure if I want to buy color e-ink screen (but this kind of gadget you cannot really tell until you have a chance to try it, it is like with the IPad first released and people was like Hey that’s a big IPod Touch, but now with the Kindle Fire and the new IPad released, they were wrong !), also don’t forget the Mirasol display from KOBO, this could be big as well.

But what is excited me is  LG flexible e-paper, it may offers a bigger size than a Kindle DX Graphite with a less thick and lighter weight, because of an e-ink limitation, newspapers on Kindle is not so popular but it comes with the size of real newspaper ?, no need to zoom in and out any more, yeah !
