Microsoft and Palm Treading Water While Other Mobile Platforms Grow

It's a great time to be in the smartphone business, unless you're Microsoft or Palm. According to the latest data, they're hardly doing any business at all.

This chart from Fierce Developer shows that while Apple and RIM have been booming, and Symbian and Android have shown decent growth for smaller players, Palm webOS and Windows Mobile have been largely stagnant. Microsoft even managed to lose market share between May and July. At the rate this is going, the two carriers will need some drastic changes to stay in the game. For Palm, the answer could be as simple as an expanded or refreshed product line. For Microsoft, though, it looks like a fix won't be coming any time soon.
