I guess the map making must have been a big 4th Edition show stopper for a lot of DMs lacking the Photoshop skills or the money to buy miniatures and dungeon tiles. It takes quite a while to build battle maps in 4th Edition. I think the time is well worth it, but not everybody would not agree to it.
Meh, just do it the old-fashioned way, draw a map on a piece of paper, and transfer it to dry-erase when you play (or even do that before hand if its a set-piece you know is coming). Nothing WRONG with tiles, but I never liked the way they tend to constrain ones thinking about encounter locations.
