2 Must Read articles for ALL smartphone developers

I came across 2 really awesome articles today regarding development for smartphones:

• A developer's-eye view of smartphone platforms
• The cross-platform option: Web apps for smartphones

The first article covers ALL the development platforms currently available for application development for smartphones, e.g. iPhone, RIM, Symbian. The second one covers an alternative to native and interpreted applications, using Web Apps. Both are a must read.
