Internet Explorer on ipad2????

I am looking into getting a tablet to take on showings. I want something with a 10" screen or bigger, wifi PLUS 4g, and it has to have Internet Explorer so I can get on the MLXchange.

I think the ipad 2 through att would be the best option if I can get access to the MLX some how. It does not allow this from the factory but I have seen a few work arounds on the internet to allow this. Do any of you currently use one of these work arounds on the ipad or ipad2?

They said today they are upgrading the IPAD in about 2 mos for everyone buying them this Christmas.

Did they say what type of updates?

I have heard that you can partition the harddrive to run both mac and windows on the same ipad. Has anyone heard of this or tried this? Also interested in how much it will cost to do something like that?
