I've had an AX100 for a couple months and it is an awesome machine! It will fight through "some" ambient light quite well but you'll find yourself wanting the room darker for better contrast and the full effect.
However you shouldn't use a PJ as your primary display. They are not designed to be turned on and off several times a day. When you fire it up it should be left on for at least 2 hours and when it is shut down, the lamp needs to completely cool off before you strike it again. A new lamp for the AX100 is about $350. Something to consider.
Go to avsforum.com for a ton of info on front projection.
They will all tell you that for a screen under 80" you should go plasma or LCD or such. I watch 88" from 12 feet viewing distance and that is considered small. But I'm a newb at projectors and it looks gorgeous to me.
