The Bluetake BT100S-Plus is a very versatile Bluetooth adapter. It's packaged in a Compact Flash Type I format, making it usable on desktops and laptops running Windows (XP/2000/ME/98SE) and handhelds running Pocket PC 2000, Pocket PC 2002 and Windows CE 3.0.
For my testing I've used a Dell Latitude laptop, with two PCMCIA ports. Users that wish to use this device on a desktop or laptop will need a CF to PCMCIA (PC Card) adapter.

The surprise is that this device is CSR based, and runs with Widcomm drivers. Since I've already installed these drivers on this laptop, using the Bluetooth BT100S-PLUS was easy. Still had to install the drivers though, because of device identification. But this was easily done .
The software comes on CD, and installation is easy. The version distributed is 220.127.116.11, which is pretty recent, with good support, including the profiles we'd expect in this version.

I haven't tested the card on a Pocket PC (the ones I have here all have Bluetooth built-in), but the software is the Widcomm, same used in the new HP Windows Mobile 2003 Pocket PCs (meaning that our Bluetooth Guides for Windows Mobile 2003 will work just fine).

Because of the versatile form factor, this product have an advantage over USB dongles. Users can move it from a laptop to a Pocket PC and use Bluetooth in any environment.
Performance was acceptable, with a weak signal from a 8 meters distance, but this while using it through walls. Mind you my H3970 has no problem with signal strength over this distance.
In terms of software it's good to know that a de-facto standard is being used in both platforms. The BTW-CE is widely supported because of the iPaq line using it, making it easy to configure and use Bluetooth on a Pocket PC.
