I'm fine with how the Karma UI works and even how it looks. Okay, touch thinner would have been great but apart from that it's okay.

What annoys me constantly is that damn Hitachi drive inside going nuts and requiring me to get a paperclip out to reboot it The constant retries and backlight staying on means that the Karma gets really warm and the battery gets drained. Only ever had to do the smack the Karma hard trick once.
