Garmin 296. Should I retire my 295?

The new Garmin 296 has been out for about a year now and the fanfare
seems to have subsided. There are seldom any new posts about it.

I was looking to trade in or replace my 295. I have one of the first
ones in my Bonanza and it is a great tool, I'd hate to be without it.
It is 4 years old now and I wanted your thoughts on:

1. trading it in on a 296.
2. buying a 296 and moving the 295 to the car.
3. waiting for something better.

You guys that have been using them for a while now, what do you think?
Is there a substantial performance difference over the older model?
Anyone have a insite as to what might be coming next?

Thanks,

Bob
