Well, MIMO is probably the future in one way, shape or form. But, unless you are having issues with networking where you are, I wouldn't spend too much more to get a MIMO device today. If you are doing lots of large size file transfers, or have a difficult area, house or great distance to go I would then look into MIMO devices, or better yet a pre-N from like Belkin.

But, I do not think there are laptops with MIMO built-in, so you are going to have to use a secondary card, (read, sticks out of the side) and would have to get new PCI cards for a desktop.

Later in 2006, the landscape will be much more clear
