There are only three things that I absolutely need to have on a mobile device: my PIM data, my email, and FlexWallet. In light of that, I can't tell you how excited I am about this - I've been using FlexWallet for a long time now, and it's always frustrated the heck out of me that there was no Smartphone version of this application. In some instances I was bringing my Pocket PC along for the sole purpose of using FlexWallet. I've also been burned several times by not having my FlexWallet data with me and needing a username/password combo that I hadn't committed to memory.
With the release of
FlexWallet 2005 (affiliate), the software has taken a quantum leap forward and is much more user-friendly than ever before. And now the developer has told me that they're hard at work on a Smartphone version (shown below). Awesome!
No firm ETA, and I'm not sure how he's going to get around the lack of a file sync conduit (shame on you Microsoft for leaving this out!), but I'm looking forward to this a great deal.
