Well, realistically, since the X1 is so much cheaper than the Sony, you could buy the extended 6 cell battery and probably get similar battery life. The X1 is lighter too, so even with the extended battery you're not carrying more than the TX. I would agree, though, that the screen of the X1 isn't the best. It's clear/bright/nice, but does lack the contrast of the glossy screens. It is bigger by 1" though
