I completely agree with you. I've been itching to get a new phone for no other reason than to get a new one, but nothing has really gotten me too excited. I have no use for LTE, and I love the DInc's screen size.
I also love what Sense brings to the table, namely scrollable widgets. I'm curious to see what future versions of android bring to phones. If scrollable widgets from tablet honeycomb make their way to phones, I can really see myself trying to find a stock phone (or probably even convince myself to use a rom for longer than a day).
All that said, there is one thing I am starting to dislike about my DInc, gaming. While it will run most any game right now perfectly fine and likely will continue to for a while longer, it's already fallen flat on it's face with the higher tier games. Dungeon Defenders literally brings it to a crawl on the first level and a few Gameloft games do have issues on the DInc.
But that's the great thing about tech these days, there's always that complementary item and for me that's the Xoom. Scrollable widgets and a fantastic looking UI (Thank you Matias Duarte!) and hardware to back it up. I don't see myself getting a new phone anytime soon, but it may be getting replaced in a large part of my life by a tablet.
