Now that it seems that the magic definitely isn't getting flash, both of these phones just became more attractive to me but I still don't think either is worth it. As a ps3 fanboy I like some of the integration potential as well as the hardware specs of the x10 but the ui seems overdone and launching this phone at 1.6 is foolishness.
I have to assume that the Acer's snapdragon is underclocked for battery optimization which makes me wonder what the hell is wrong with their battery optimization. They're paying the same for those chips as every other manufacturer so underclocking them is just devaluing their product (and thus their margin) so you'd think that they'd find other ways to make the battery last. HTC and Motorola obviously have.
At the end of the day, unless the x10 gets 2.1 sooner than later, I'm waiting for something better.
