I wish I had seen your post before I bought the Tom Tom GPS at Staples for $149 a couple of weeks ago. This one at $169 (less $20 coupon when order online) seems to be a better featured unit
For old guys like me who doesn't have good eyes...
I'll stick with my Microsoft Street & Trips + Receiver + Laptop....
13" vs 4.3" display...
Same Price (On sale $99.00)
Easy to travel with (have to bring my laptop for business trips anyway, the receiver's size is similar to an ipod shuffle)
Touch screen control (My laptop is HP TX1000 series)
