Microsoft or Google hand held gps device?

Is there any reason why Microsoft doesn't come out with a hand held gps device with Streets & Trips on it? Or even Google? I think if Microsoft Streets & Trips or even Google with their online maps came out with a hand held gps device they would clean up on the hand held gps device market. In my honest opinion no other gps software comes even close to Streets & Trips or even Google maps.

I'm pretty sure neither Microsoft nor Google sees the handheld GPS market as anything significant to go after. To the extent that it matters, Google already has handheld software for smartphones that have GPS capability. It turns them into handheld GPS devices.

My daughter and son-in-law both have iPod Touch devices with Google Maps on them and they work pretty slick as long as they have wi-fi connections along the route. I don't know if the handheld application works like Google Earth on a laptop, whereby you can preload the disk cache on the laptop with maps of the area you want to navigate in so you don't need a connection.

With that application available, Google doesn't need to get into making handheld GPS hardware to get people to use their maps.

I don't know if Microsoft has any similar plans to make it easy for smartphone users to connect to Bing Maps for navigation.
