Any of those laptops should work fine. I am using Windows 7 installed on a used laptop I got on ebay for about $100.

If you purchase the Micropod 2 unit and need some assistance, or have some questions, I will be happy to try my best to help. I am however not an expert. I am just a Crossfire owner who is unhappy with my dealers (lack of) service. They charged me $75 to say they couldn't relearn my TPMS, and then estimated an additional $300 (parts only) to replace a TPMS module that I didn't need. It felt good to be able to do the work myself, and not have to depend on them. That alone was worth the money I spent.
