 Also keep in mind that vendors tend to stop upgrading firmware after 1-3 years from the release date. This is because they generally feel pretty confident and stable about the code as their bug reports slow down and die off. By the time you'd want to sign a contract with PARSEC, you'd probably be well out of this period. So, to be fair and compare apples to apples, the OEM vendor isn't going to give you firmware updates beyond a certain point either, even despite having the legal means to do so.  Also keep in mind that vendors tend to stop upgrading firmware after 1-3 years from the release date.
