Anand Iyer (AI) posted the slide decks of his Smart Client webcasts with links to each webcast. The top on my list to check out is Mobile Device Smart Clients. Now that my Axim is getting its memory back I'm getting antsy to see a .NET app running on it. Sophisticated mobile device support was one of the selling points for the Winforms application I've been building.
p.s. Thanks to Frank La Vigne's blog for making sure I didn't miss AI's post.
