There ARE tiny WiFi+BT chips out there that share the same antenna. They're usually accessed via two different interfaces, like a SDIO bus and a UART. But IIRC the SDIO bus is a one-bus, one-device system. I think CF is as well, though I'm not sure. What that USB device perhaps does is have an internal USB hub which connects a WiFi RNDIS module and a Bluetooth RNDIS module, all enclosed in a single device. When you stick it in your PC or laptop, Windows enumerates two different devices as seen by the USB hub. Anyway, this is probably way more detail than anyone cared to know, but it explains the above question. -- Judie, it's great to find your other site. I was beginning to think the web had lost you, which would've been sad. Best of luck with Gear Diary!

It’s in beta, but it’s being released.

This should be a nice way to move data.

We'll see if I wind up keeping it (for the Navigation, if nothing else), or if it goes back within the return period... Yah, I know. :-( I am totally spoiled by VGA, too.

We’ll see if I wind up keeping it (for the Navigation, if nothing else), or if it goes back within the return period…

Somewhat disappointing, at least for me. I continue to wait for someone to surpass the Doug benchmark for PDAs similar to this: Ye Olde Tapwave Zodiac, with a 4" 320x480 screen, 128MB of memory, built-in Bluetooth, and <i>two</i> SD slots. Same weight as this new HP device. Not to mention shoulder buttons for convenient eBook reading. I mean, geez, how much longer do I have to wait for someone, <i>anyone</i>, to even <i>match</i> those specs, let alone pass them? It's beginning to be pretty depressing, honestly.

Excellent application/removal and perfect clarity. A lot cheaper than Boxwave and PPC Techs too. I will be looking forward to that rx5915 review as well. My dad and I have tried two GPS systems recently (a TomTom 710 which was excellent but missing a few warning features, and a RoadAngel 6000 which had the warnings but was utter junk) and have returned them both. The rx5915 (if it hurries!) looks to be an excellent unit. I have previously bought EXIM branded screen protectors off eBay, and they can’t be beat. Excellent application/removal and perfect clarity.
