that things are:
1.charger connecting.it would be great if the phone could charge when android is booted.
you boot the android,and you can't charge him,bla bla...anyway,its the second main problem.
3.keyboard.its not such a big problem,just good to mention.
ok,im sure that developers will work it out.its ok,cuz xperia x1 android is still work in progress.we should all say a big THANK YOU to developers!
