There are now a few devices with Bluetooth in them. Sony has had a Viao with it in for a while. 802.11e is not gigabit wireless. .11e is quality of service enhancements to the .11 MAC. You may be confusing it with .11a - 54Mbps at 5.2GHz or the new .11g giving 54Mbps at 2.45GHz. Some people (Proxim) have .11a cards that can operate at 108Mbps. This will have a reduced range though as they probably halve the forward error correction somehow - maybe by increased puncturing. .11 without .11e is worse than Bluetooth for certain data types. For example it cannot carry isochronous data. Bluetooth was never meant to compete with .11 and was designed for a different purpose - mobile phones. Wanderering around the UK's high streets a lot of phone shops and a couple of the bigger consumer electronics chains are now selling Bluetooth enabled stuff.
