I hated minis with a passion that cooled somewhat when I couldn't get anyone to play without them during 3e. Then I just found them boring and distracting. I felt like they pulled me up above the action when I wanted to be looking through my character or NPC's eyes. On top of that, as a player, I found that GMs would use them as a shorthand to avoid describing the area that combat happened in. I even fell into that trap, and I hated myself for it.
On top of that, movement in 3e was mostly dull- you move up to a foe or into a position to get everyone with your spell, then mostly stayed still until grim reality made you move again to do it all over. It felt like a really lame board game to me. It's a major reason I stopped writing for and running 3.x.
The situation in 4e feels different. There's a lot more going on on the mat, and with things like stunts (I could never get players to let me include them in 3.x) zones, etc, it's easier for me to go back and forth between being above it all and down in the thick of it. It all feels more dynamic now, and that's what I needed. I'm cool with minis now.
