Reading PDF On A Mobile Device - Kindle, Crunchpad, iTablet, or Another eReader

Here is an IM conversation I had with Dave the Mobile Warrior (yes, there really is a Dave the Mobile Warrior) about reading PDF on a mobile device.  Going over it, I am excited about what's coming in the 2nd half of 2009 and early 2010 as far as mobile devices are concerned.  

11:15:22 PM Dave The Mobile Warrior: i think i want a dx

11:15:44 PM Me: dx?

11:15:48 PM Dave The Mobile Warrior: kindle dx

11:15:57 PM Me: haha...what happened?

11:16:07 PM Dave The Mobile Warrior: i have so many pdf that i don't read

11:16:29 PM Dave The Mobile Warrior: but i should really wait for the plastic logic reader to come out first

11:17:28 PM Me: yes...how much is that?

11:17:34 PM Me: just wait and see.

11:17:56 PM Dave The Mobile Warrior: i don't think they announced it

11:18:33 PM Me: oh, I see.  just wait...

11:18:52 PM Me: kindle you can do more though.  I really want to see how it works first.

11:20:51 PM Me: i like the unlimited Internet access.

11:21:19 PM Me: it has a browser, right?  so I don't understand why people need to subscribe to newspapers when you can use the browser.

11:21:22 PM Dave The Mobile Warrior: it would be even cooler if you can tether it

11:21:38 PM Me: i'm not greedy 

11:21:59 PM Dave The Mobile Warrior: the kindle formatted ones are probably nicer

11:22:08 PM Me: but you can still read it for free, right?

11:22:15 PM Dave The Mobile Warrior: i presume so

11:22:55 PM Me: wait for the iTablet too.  I don't want to go through the frustration of pinching and spreading like I did with my G1.

11:23:10 PM Dave The Mobile Warrior: oh, i already forgot about it

11:23:14 PM Me: yeah.

11:23:16 PM Dave The Mobile Warrior: and the crunchpad 

11:23:26 PM Me: haha...I forgot about that.  

11:23:36 PM Dave The Mobile Warrior: but the dx is the only "real" product 

11:23:40 PM Me: so, dx, plastic, itablet, and cp.

11:23:43 PM Me: right.

11:24:04 PM Me: CP, if the battery life is good, is a must buy at $300

11:24:13 PM Dave The Mobile Warrior: define good

11:24:17 PM Dave The Mobile Warrior: 5 hrs?

11:24:21 PM Dave The Mobile Warrior: 10 hrs?

11:24:45 PM Me: 6-7...again, I'm realstic.

11:24:50 PM Me: 10 would be preferable.

11:24:59 PM Dave The Mobile Warrior: they will publish 6-7 and you'll get 3-4

11:26:10 PM Me: eah...min of 5 with regular use...real use...not with the screen dimmed or something like that.
