The App Store celebrated its second birthday last Saturday, and what an amazing run it's had: 250,000 apps and over 5 billion downloads. CNET has a great article on this success and how it's influenced the industry. AND it talks about what Apple can do to maintain and build on its success. Meanwhile, how do you find what you want in this sea of 250,000 apps? PCMag has a very helpful article on their favorite apps. They group them into topical themes, such as Top 40 Free Apps and 6 Great Travel Apps. Some of the collections are a bit dated, but others are still relevant.
