I'm on the go all the time, and sometimes that makes it hard to stay connected. I could carry my laptop with me everywhere, but that can be a pain, especially when I am on my bike. To meet the demands of my daily life I have constructed a lightweight, ultra-portable, Linux-based computing solution. I use a Nokia 770 tethered to a Nokia N75 mobile phone (when Wi-Fi is not available) and a Bluetooth PDA keyboard.
