Gadgets for consideration

Kevin recommended the first two and the third I found after a little surfing:

• SanDisk’s MultiCard ExpressCard Adapter – Kevin’s review – and now only $11.36 on Amazon – a no-brainer and Kevin just vouched for its download speed.
• Mainnav MG-950D Sport Bluetooth GPS Data Logger / Cycle Computer – link – The cycle computer is tempting but an unlikely purchase – not enough offroad rides to warrant that since Bikely takes care of my road route plots nicely.
• ?Locosys Genie BGT-31 Waterproof Sport Bluetooth GPS Data Logger with SD Expansion Slot – link – might be just what I need for my field trips – no Mac OS X support indicated but I think as long as it provides NMEA data, I can convert that for use by Google Earth.
