Yeah, don't even remind me about the wifi nightmare that was the iPad prior to firmware 3.2.1. Just a joke. If there's one thing Apple can't do properly (among many things), it's things to do with wireless. Whether it's antenna issues, wifi issues, BT issues (iPhone 4), iMac wifi issues, iMac Bluetooth issues, MacBook Pro wifi issues, MacBook Pro BT issues. The list goes on. And yes, that's just MY experience.
I still love my Applez, but I sincerely doubt any of us will have problems with the Kindle 2's wifi. It amazes me that companies STILL have trouble with wifi - probably one of the cheapest and simplest chips in a computer!
