I received mine today; it doesn't have the power issue that others have written about. I do hope that they "fix" the WAAS issue when restarting the unit. Although, with WAAS turned off I was still getting 9ft of accuracy outside. ...maybe it save battery life with WAAS turned off.
on a side note... topo US 2008 hasn't changed much from the previous version, aside from the shaded terrain on the PC (no change on the GPS display). But the North American NT software on DVD has changed so that you need only one map per state (except TX - 2 maps). Previously states were in a bunch of pieces.
one last side note... Sanyo Eneloop rechargeable batteries are excellent. (Circuit City or Thompson Distributing online) A couple of sets of those and a BC-700 or BC-900 charger and you're golden.
I purchased from TigerGPS and I would do business with them again.
