One of the best resources on the web I’ve been using recently has been slideshare.net. Everyone is uploading their presentation there from a conference or user group meeting and it turns it into a flash presentation that you can embed into your site (even wordpress.com blogs). Here is one I found titled “What is Android” by Erik Fields from Think Interactive and how it compares to the iPhone SDK in terms of developer platforms and user experience.
P.S. My co-worker and I are hosting an Android developer panel this Friday at 2pm PST / 4pm CST on designing, developing, and distributing your Android app. Tune it live to http://blogtalkradio.com/motodev. Questions will be taken online at http://tinyurl.com/motodev, via twitter @motodev and by calling in during the show at (347) 826-9350. Hope to you can tune in.
