Microsoft at MIX 2010 re-emphasized that Windows Phone 7 Series devices wouldn’t be backwards-compatible with current Windows Mobile applications. "We do recognize there’re a lot of folks who’ve been writing apps for Windows Mobile for some time," Larry Lieberman told eWEEK. "But we recognize that the landscape has changed, and as we’ve been looking at stuff, we had to drastically change our game, and really the only way to do that was to look at what we were offering and what we could do to address this in a competitive accelerated manner." Lieberman said new paradigm for Windows Phone 7 Series could provide tools for resurrecting Mobile apps in updated form: "The development platform gives people a lot of opportunities, and they may be able to recreate a lot of their previous work in a very accelerated manner." Part of the reason behind a lack of upgrade path for apps, Lieberman added, was the timing required to push Windows Phone 7 Series to market. "This product was delivered in an incredibly accelerated timeframe," he said. "If we’d had more time and resources, we may’ve been able to do something in terms of backward compatibility."
