I agree that without access to charging, a PHEV does not make sense. Since we all want to run on electricity all the time, you will find that you will top off the battery at any chance. I have free level 2 charging at work, so plug in the morning, even though I only used 15% of battery on my 5 mile commute. I plug in at home on the weekends, because I never know how many miles I may end up driving on a Saturday or Sunday.
The other reality is that we have no idea of the market value of our PHEV's in 3-4 years. It is highly likely that there will be BEV's and PHEV's with much longer EV range by then, making our EV range seem obsolete. However, we are all betting that a luxurious Honda (quality, reputation) with great gas mileage in HV mode will still have good value even if only considered as an HV vehicle. Getting the $7500 fed credit made that calculation make sense for me.
By the way, when purchasing, I asked the dealer about Honda special lease terms. They laughed because the lease residual value was so low - Honda does not think these cars will be worth much in 3 years. An Accord Hybrid would be higher residual going by the book.
