While I was covering Macworld Expo one piece of tech that proved invaluable was the SanDisk Ultra II SD Plus, a combination SD memory card and portable USB drive that's a must-have.
The Ultra II SD Plus is worth a look for anyone that carries a Treo smartphone or SD-equipped digital camera.
Have you ever been in a meeting and someone asks if you have a USB drive? The tiny flash drives are so darned handy for quick file transfers but the problem is that I never seem to have one when I need it. I also have a habit of losing them pretty fast. (Isn't it kind of ironic that we're returning to sneakernet in this day of wireless everything?)
The Ultra II SD Plus is super convenient if you have a Treo because you can keep it in the SD card slot and bust it out on a moment's notice. They also work great in cameras too because you don't have to remember to bring a cable. Simply pop put the card, fold it down and plug it into an available USB port.
The only downside that I can see is the potential for breaking the little hinged flap, but so far mine have been rock solid. An added bonus: they only cost a little more than a regular SD card, I purchased a 2GB version for around US$70 plus shipping via Froogle. I replaced two of my normal "blue" SD cards with the Ultra II's and haven't looked back.
Too bad the iPhone won't have an SD card slot.
Damn! I knew I couldn't write a blog post without bringing up the iPhone ...
