Kindle vs Kindle DX

I just came back from Borders after treating myself to Benjamin Graham's SECURITY ANALYSIS. It was available for 40% discount on Memorial Day so I decided it was too good of a deal to pass. The only thing is, it's really bulky and heavy. I went online at Amazon to see if it's also available on Kindle and I found out that the new Kindle DX is coming out!



Aww mann, Kindle DX will be out in summer and looks really really good. At 18ounce, that's about 500g, the weight of a filled 500ml water bottle. I think I'd very much like the bigger screen and larger area but I think 500g is a little too heavy for holding and reading on a train (say, when I return to Singapore - yay yay, can't wait to return home!). The Kindle 2 is only 280g, but then it kinda looks too tiny... What would you do/ choose?

Actually I really like reading a physical book and being able to highlight things that speak to me. But the problem comes with storing these books and esp. having to type out these highlighted stuff to bring them as tidbits of wisdom with me whenever I relocate from place to place, which is ever-so-often. So being able to highlight, scribble notes etc. and have it all appear instantly on the Kindle is especially appealing to me. And I just like having my 'library' collection at my fingertips. :)

Nonetheless, USD$359/$489(!!! that's a 36% premium to Kindle 2) feels kinda steep to pay for an electronic screen, esp. since I won't get to download the books after I leave the USA so I will have to do a mass download of everything I want prior to leaving. Ugh...how how how???? Ok, I've spent an hour agonizing over the Kindle..time to hit my CFA books. So if I pass, this shall be a perfect Birthday-come-Reward present- this is just about the ONLY thing I REALLY want, less the iPhone which I can't buy because of the 2 year AT&T contract (I hope I'll get posted back to Asia by the end of the year). :) Please lend me some inputs- what do you guys think?
