BinLadenMyHero asks: "The company I work for, administrating their Linux email server, wants to buy me a GSM device so I can access the server 24/7 in case of any trouble. I usually work with a text terminal session over SSH (mutt, vi, bash, screen, etc..). The Nokia 9500 looks the best for the job (640 pixels wide, and a qwerty keyboard), but is a bit large to carry everywhere. Sony Ericsson 910 is smaller, but that small screen size and keyboard can make it less useful. Treo and iPaq was also considered. Any advice on which device to buy?"
