I have a dedicated HP Mini 5103 running INPA, NCSExpert, WinKFP bundles and PA soft only on Win 7.....and nothing else.
It stays on the X5 wherever I go..........and has saved/served me from getting out of trouble....alot of times.
While ISTA-D / ISTA-P and another copy of NCSexpert on Panasonic Toughbook.
For me.....INPA is the best on diagnostics and monitoring....I used it alot.
