I just ordered a 14z laptop with the 802.11n WiFi option but unfortunately for some reason this pushes the ship date out another 8 business days. I would really like to get this thing by Christmas but with the 802.11n option the estimated ship date is 12/29. I would go with the 802.11g for now if I could later upgrade back to the 802.11n but I wasn't sure if this was feesable or not. I read somewhere that the antenna config was different for the 802.11n which sounds more painful than just changing the card out. Does anyone know what would be involved with doing this upgrade later? Thanks.
