I keep being asked which is my favourite out of all the IWBs I have used. I can't say I have a definite preference for one particular model as they all have features I like (and don't like) so here is where they stand at the moment as of August 2009!

If I was choosing for Software - Activboard
If I was choosing for Price - Mimio
If I was choosing for interactive features (uses both hands and pens) - Smartboard

I can't ultimately choose one product!
Now, if only somebody could come up with a product that incorporated all three...
