After all that hype up, hype down, I simply WANTED to USE bluetooth technology, switching from the "design stance" to the "intentional stance", hoping/assuming that
- any sufficiently advanced technology is indistinguishable from magic (Arthur C. Clarke's 3rd law) - any technology distinguishable from magic is insufficiently advanced (Gregory Benford's corrolary). Here are some experiences from a semi-literate user: Ignore the fact that the things are still too expensive. Think of bluetooth as an invisible cable, not as a wireless network. And like with cables, there may be issues with compatibility, set-up, etc. And like with cables, it may also run trouble-free. |

Ericsson mobile phone T-39M
Phone with headsets/handsfree: works fine in principle. Having bluetooth enabled constantly at the phone shortens standby time to one third. |

Ericsson headset HBH-15;
Pama plug 'N' go 4 bluetooth
Headset and handsfree: works fine in principle, with Phone and with notebook. The headset looks too much like "star trek", and I don't want to walk around like that (social acceptance/customs issue). Possible improvements: waiting for a much smaller invisible device, with speaker and microphone into (not onto) the ear, or built into the glasses (wearing glasses is socially acceptable). |

AVM BlueFritz! USB, plugged into the Fujitsu P-2110 notebook
Adds bluetooth capability to the notebook. Disadvantage: The USB dongle extends too far out from the rear end, where the USB connector is located. Built-in (not available from Fujitsu) or a PC card (mostly inside) would more convenient. Using the headset as microphone/speaker for the Notebook/Bluefritz!USB finally works. Send me a mail if you have problems. |

AVM BlueFritz! AP-X ISDN access point, connected to the phone line.
Had some trouble to set it up, now it connects to the Notebook with the BlueFritz!USB. I can walk around, sit anywhere in my appartment, and be connected to the internet. It's good that BlueFritz! AP-X and USB (as opposed to many other USB bluetooth devices) is powerful enough (bluetooth class 1, max. 100 mW, nominally good for 100 m distance) to connect through the concrete/steel walls of the building.

Anycom Compact Flash card CF-2000, in HP DJ-450CBi pinter Notebook through BlueFritz! USB to printer: everything works fine. Phone and printer: should work, does not. Don't know why. Since both also have infrared, I can print phone content (business card, etc) through infrared instead of bluetooth. |

EPoX presenter BT-PM01B
Presenter with forward/backward buttons, joystick-mouse, mouse buttons, and laserpointer. Fine with Anycom Card in Fujitsu (in CF-to-PC-card adapter) via SPP/COM5, does not work with AVM BlueFritz. |

Except for the access point, everything can run on rechargeable batteries. Which means: lots of cables, power plugs and hardware needed to re-charge batteries from time to time.
Except for the access point, everything can run on rechargeable batteries. Which means: flexible, mobile, autonomous bits and pieces, high potential for interactions (complex interaction of devices). Exactly the design ("Gestalt") that I like, not only for bluetooth devices: CompleXimple. There are so many possible combinations, I don't use them all. Already possible, I just don't need it: - Notebook/BlueFritz! USB and mobile phone to synchronize e.g address book and calendar - from Notebook/BlueFritz! USB to mobile phone through antenna to service provider to the internet - two phones, exchange business cards - two computers, local network, resource sharing (printer, internet, DSL) Nice to have, but not yet possible: - mobile phone as cordless phone to BlueFritz!
