If you do a lot of IFR, don't over look JeppView/FliteDeck. I have
previously posted my setup with a touch screen monitor & portable PC.
FliteDeck has the best IFR moving map. Since I fly mostly around
California, I pay only $295 for initial and $195/year thereafter. And
that is for moving map & all charting data.

As for AI & WX, JeppView does not have them & I have no experience with
product of these type. But, JeppView is Windows based and should be
able to run alone side other Windows programs.
