Are you really comparing typing on a PC keyboard to typing on a BlackBerry? My thumbs can only "type" so fast, but sitting at a keyboard I'm somewhere around 100 wpm. It feels like two completely different activities. At a keyboard, capitalization happens automatically without me even thinking about it.
It's not a matter of bad habit, it's a conscious choice. When I'm IM'ing with friends, I typically type all lowercase (but with good spelling and punctuation) because it's what they do and it seems less formal. When I'm typing an email or an HN comment, the capitalization just happens.
