Android synci'ing PIM with Lotus Traveler: TouchDown

I need a phone that can run apps.
Until today I thought that what i needed was an iPhone.
Now I will consider an Android-based device instead.
And what made me change my mind?

It looks like I will be able to have Lotus Traveler-based synchronisation between an Android device and my Domino email.

I stumubled upon Jake Howlett having created his own app on his HTC Hero (which runs Android as its OS): My Hero To The Rescue. And that is a great thing about Android - it looks a lot more open to me. I would be able to create my own Java Apps.
I had a look at how to create my own apps for the iPhone. It looks like I would need C programming skills. Forget it.

I also need an app for Geocaching. There are apps for both the iPhone and Android. A quick Google-based research shows this: GeoBeagle – Geocaching Android Style.

But I am addicted to the Lotus Traveler synchronisation. I have it on my Nokia E65 (running the Symbian OS), and it just works. No glitches.
well, Android is not on the list of currently supported device OSes for Lotus Traveler, and that is the reason I haven't really looked very much into what the Andoid has on offer. I did some more research, and look what I found:

A product called TouchDown from a company called Nitrodesk. List price is currently USD 9.99. And the feature-list is long.
And in a pdf brochure for TouchDown I found mention of Lotus Traveler 8.5.1:
Supports multiple servers

• Exchange 2003/2007/2010
• Kerio
• Zimbra
• Lotus Notes Traveler 8.5.1 (Beta)

It's beta, yes. But it is certainly interesting.
