The same question can be asked to IPod owners when the nano came out,
to 5 Mpixel digital camera owners when 8 Mpixel came out,
or to Hidef TV owners with PyPbPr only inputs when the HDMI inputs arrived, or cell phones owners with only a still image camera when cell phones with MP3 players and full motion video became available.

All of them happened to me,. Of course, the 2005 HCH vs 2006 HCH, also happened to me.
Do I feel the pain? Do I feel Hybrid-envy? Yes, but...........

There was a very interesting article by Grand Digital Guru Ken Pohlmann. He basically said: "In technology, one will only stay on the cutting edge for a period of a few months, if so, before something else newer and better comes out. So enjoy what you've got now, and don't let digital-anxiety overtake you".

Just like you, I also love my 2005 HCH. And like you, I plan on getting a newer generation hybrid when they become available. In the meantime, I'll just enjoy it.
