Naturally, I contrast this with Apple's behavior with their signature legacy apps on the iPad. They rewrote and re-imagined both the iLife and iWork suites for the iPad first (for the most part), then rolled them down to the iPhone.
However, Apple did this over the course of years. The iPhone debuted with limited read-only mail attachment support, but left productivity apps to third parties. iWork was introduced with the original iPad (early 2010). iMovie accompanied the iPhone 4 (late 2010). GarageBand and iMovie for iPad accompanied iPad 2 (early 2011), and iPhoto debuted next to the first iPad with Retina display (early 2012).
Apple didn't have the pressure on them to support everything on day one. However, they did establish what was possible through their actions. They led the way by being model iOS citizens.
Microsoft has a lot more pressure on them to do everything, be everything from day one, partially because of their dominant market footprint in business, and partially because Apple relentlessly showed what should be possible in terms of productivity on a tablet.
