(The same goes for laptops; get an
inexpensive Bluetooth USB dongle to connect your Windows PC to your
cell phone wirelessly and surf the Web from the park or even the train!)
Now, some higher-end PDAs come with WiFi or Bluetooth support
built in, while others have special expansion cards that provide connectivity.
You can get a WiFi SecureDigital (SD) card or a Bluetooth SD
card that will fit in many PalmOS and PocketPC handhelds, but if you
have only one SD slot, you??™ll have to remove your memory card. If you
need the wireless support, you may prefer to replace your PDA with one
that has WiFi or Bluetooth (or both) built in, and do away with the
awkward protrusion of the expansion card.
Digital camera
Some high-end digital cameras now have WiFi options, allowing you to
send your photos to the hard disk in a nearby computer wirelessly,
either in batches or immediately after you take them. Unfortunately,
this only works in the studio (as opposed to outdoors), where you??™d be
in range of your wireless router. At the time of this writing, there are no
wireless cards you can conveniently insert in place of your digital film,
but it shouldn??™t be long.
Video camera (webcam)
Get a WiFi-enabled Internet video camera, and place it anywhere within
range of your network. Then, use your PC to view a live video feed wirelessly.
Or, use it in its server mode, and let anyone in the world see how
much coffee is left in your coffee pot.
