Personally I wired my basement home office for multiple runs of cat5 runs after I got cable modem last year. I am going to pull additonal runs for future computing devices in kitchen and study up into attic and back down as soon as weather in NJ gets cooler. My feeling that gigabit wired ethernet will replaced 100 megabit ethernet by yearend. Gibabyte cards are now about $40 and wireless cards with same level of performance will be much more money.
