Yes, yes – you knew that already. At 546g (250g more than the 6″ Kindle International) it’s still less than the 730g the iPad from Apple weighs in at. Half the weight of a netbook…
The Kindle International DX (KIDX from now on) doesn’t have the left-hand side page-turn button (no big worries if you’re right-handed), but from a functionality perspective, other than a bigger screen, it’s pretty much business as usual – PDFs still can’t zoom, web browser’s still the same, text-to-speech is still a gimmick, and still no (Sony) ePub support. $489 is the asking price, $230 more than the 6″ Kindle…
Rather stick to the 6″ — holding the 9″ Kindle to read is more exercise than relaxation…
