Terrible poll.
I loathe miniatures for TT RPGs with a deep and burning passion, yet I've found that 4E and to a lesser extent 3E required me to use something very close to miniatures to actually play properly. Anyone who claims 4E can be played easily without a battlemap and counters of some kind (whether minis or not) is frankly living in an exciting fantasy-land. It's a game very clearly and intentionally designed to force use of minis/counters, moreso than any game that didn't actually come with miniatures that I've ever played, and hell, moreso than some that did!
The funny thing is that I love miniatures for wargames, and have a large collection of WH40K minis (and much smaller WHFB one and a few other small collections).
It's just that I've never seen D&D-oriented fantasy miniatures which didn't trigger every single "FUGLY!" alert in my aesthetically-oriented brain. Maybe there are some out there, but they sure ain't the super-fugly official D&D minis. I've also found that my players dislike minis, and that we game better with wildly inappropriate minis than half-accurate ones (i.e. better to use a robot with machineguns on it to represent the swashbuckling human rogue than a halfling thief mini).
For 4E I'm planning to finally bite the bullet, and instead of working with photocopied/printed grinds and the like, buy a cleanable battlemap of some kind and use some pre-prepared counters (not miniatures!). One thing I read which I liked even more was the idea of using a battlemap program shown on a decent-sized modern TV with a couple of laptops to move the counters around. Sadly I don't have a couple of laptops!
