ermm....do blackberries count?
i'm definitely on my computer at LEAST 8 hours at work everyday...especially when i don't have too many meetings. when i come home, i usually spend 3-4 hours on my computer unless i go out. its a shame, i want to get back to reading, but i'm addicted to surfing the web! i shop, browse ebay, read blogs and news and message boards, emails, etc. always something to do!
