On my Arrive I frequently have the issue with initial-letter capitalization. I usually find if I tap outside the field or backspace to get it to do it right. It's not irritating enough to complain about, but it does bother me once in a while if I'm in a hurry... mostly because I'm obsessive about grammar and spelling.

I also notice a huge delay in the Search function, but I assume it's because it's grabbing your GPS signal in order to presearch for the Scenic features. You might try disabling Location serivces and seeing if it makes a difference for you.

Never noticed the linked inbox issue, but then again I purposely don't link them, because I like keeping my work/personal mailboxes separate.

I definitely don't experience Mango being slower than NoDo... aside from search, of course. In every other way it's noticably faster.
