Query: Great device, good price

My wife picked this up for me for Christmas from Costco. Good deal. The maps work great. I've been using it for a month in 3 different cities and it's picked up where I was and got me where I wanted to go very accurately.The one big drawback is that this unit is gimped on the amount of memory built into it (1.5 GB instead of the 2 GB installed in the other 600 series models). I had to remove the extra voice sound files, etc in order to have enough room to install the updates from the Garmin web site.Minor gripes: It would be nice to have an easier way to create an address book and import it into the device. Multiple stop directions are possible, but a little cumbersome as you have to pick your end destination first, then 'add' the mid points afterwards. There's also no easy way to re-arrange way points once they're set up.
