If a SQ upgrade is the sole reason to partake of this new Sony DAP, that makes sense (for me, a bit warmer SQ than the Touch 2G isn't enough reason to sell the Touch to buy the X1000). But to pay for the things that aren't so hot, especially the browser, doesn't make sense, at least not for me.
Also, as a Touch 2G owner, I use my LOD cable with the MiniboxE+ and T4 quite a bit at home with the Westone 3s and Grado SR-80s, so I lose that fantastic option with the Sony.
I also use the Touch browser (Safari) quite a bit outside the house (a lot of free Wifi here), and that's really, for me, a serious deal killer. Why even put Wifi/browser into the machine if it's gonna suck?
Also, based on these early reports (granted, they are limited in terms of numbers), there are some very practical features missing from previous Sony DAP iterations (I have the A818 as well).
Add it all up, and I guess I will just stick to the A818 when I want to hear a Sony DAP, and use my Touch when I need to have the browser option. To me, the Touch 2G SQ is excellent, as I don't get that brittle sound Soozieq mentions, especially when I move to the LOD/amp setup. I would hate to give that up, and I would have to do that to finance the X1000.
Just some thoughts for anyone who has the Touch 2G and is thinking of moving to the Sony. And thanks to Walkingman and Soozieq for all the early feedback.
