For the IE bug, it isn't that pages load slower; it's when you rotate the screen and stuff. In NoDo, the animation would be so smooth that it isn't funny. In Mango, it kinda of just stutters when it does it. I've tried reflashing a couple of times to see if that's the problem, but I dont' think that's it.
Also, TellMe works BUT it doesn't work like if there is a HINT of noise other than your voice surrounding you. I thought Microsoft was promoting this great noise cancellation feature, but apparently they didn't put it in Windows Phone (for the record, I push "Go" when I'm done speaking) because half the time it does something TOTALLY OPPOSITE of what I said (I'm American and have no accent). When it's quiet, it works. When there is a hint of wind or anything it doesn't work (for me at least). Then there are times it works SPOT ON and, other times (usually), when it's just off when it comes to speech-to-text.
