I am still very fond of my Panasonic cordless iron. It "notices" you're using it every time you set it on the cradle so it has never shut off prematurely on me. It does cool down if you leave it off the cradle too long, though - it only heats while it's sitting there. I have to adjust fabric constantly though so it's in and out of the cradle quite a bit - so far not a real issue once I learned not to just prop it up on the board when I'm not using it.
I have a little travel sized steam iron for pressing seams while sewing that I really like too, it's a "Steamfast". Just got it a few weeks ago and it works perfectly for what I need it for. Heats up super fast, although the cord annoys me. I wish it was cordless too!
