Thank goodness, Microsoft has been paying attention to the way the mobile industry is shaping up!
The app itself is fine — it’s probably not going to move the needle much for Bing’s share of the search market, but it probably didn’t take much work to make, either — but it’s the move itself that is more significant.
Microsoft is smart to realise that Apple has created a mobile app platform that people actually use. And as the world’s leading software company, Microsoft must now make apps for it — even if it looks bad because the iPhone is eating Windows Mobile’s lunch. So, nice job!
