Microsoft is launching Windows Phone 7 with a more restrictive development model than Apple. The OS is just as locked-down as iOS, and as with Apple users are only allowed to install software from the official 'marketplace'; but Microsoft also restricts what license developers are allowed to release software under, and limits how many free applications they can offer without paying additional fees to MS. The one advantage that Microsoft has traditionally had over Apple - the openness of their platforms - has been squandered. Couple that with a featureset that is competitive with the first-edition iPhone, but nowhere matches current iOS and Android devices, and you have a recipe for a flop.
