Okay so i was curious about the weight of the controllers, the old XB 360 feels heavier than the new XB1, but in reality the XB1 is 17 g heavier, and in the hands it feels lighter
XB360 = 266 g
XB1 = 283 g
Another thing to note is the sticks on the XB1, they are smaller than the old one, and has an "almost sandpaper texture" on the sides, alittle uncomfortable for my big thumps, but a set of rubber heads on the sticks made it feel alot better.
A side note is that the trigger buttons (those right above the triggers themselves), they are not natural to press as on the old controller, could become annoying when looking behind myself in racing games, and on my controller the left button seems to stick more than the right one... But thats being picky about it
And lastly the new design upgrades to the layout of the controller is much more comfortable than the old XB 360, which when using for hours made right index finger go numb, so all in all a really great controller that fits in the hand nicely.
