It's very unlikely that GPS will go away in 10 years.
So, at best you're looking at a slight upgrade - 2-3m error in position
to 1m or a bit less.
For most things, this isn't important.
You're not going to be walking round blindfolded in traffic, using tones
to tell you left/right.
And DGPS can get you better positions with the existing hardware - at
the cost of downloading a couple of hundred bytes.
Currently dual mode chipsets tend to be more expensive.
Eventually - P2 or so maybe it may be a good idea.
