That's more of an android problem unfortunately. I can't remember the exact technical explanation anymore but it has something to do with the way android handles screen orientation changes by calling up a full redraw every time you do it. iOS in a side by side comparison handles this differently and noticeably faster on tablets.Transition between landscape and portrait seems slow on one of the videos I saw.
my guess on why they left it out was because they intended to do an all aluminum body at first this being an HTC device and then decided to switch to a polycarb for whatever reason (probably cost related). Either way they problem ran out of time to integrate wireless after. Thats my guess anyways.
Sadly again no SD card support and non removable battery..
Also 2gb is a bit underwhelming, I like the ratio a lot but I'll be waiting for the next Asus transformer
Removable battery is a concern for you for buying tablets???? 0_o
Yes I have yet to find one with a removable battery
I can tell you from first hand experience the SHIELD Tablet does have a very nice display w/HDMI out which is also a huge bonus!The shield while nice doesn't offer QHD
