I know how you feel, I also dislike that mini-game a lot. I'd rather go back exploring in ME with the Mako (as a side note, I still preferred the Mako over the Hammerhead). When I first played ME2 I honestly thought that eventually during the course of the game's progress we would eventually be able to upgrade the mining scanner.
When I saw that Miranda offered such an upgrade I almost jumped in joy like a schoolgirl, only to find out the next time I scanned a planet that it barely changed anything (it simply increases the speed at which the cursor moves on the planet's surface). I for one was thinking something more substantial for a scanner upgrade, along the lines of a complete surface planetary-wide scan that would take perhaps a few seconds and then would discover the most important patches of resources automatically, only to leave the remnants to be found manually if so desired. I actually sent this very idea to BioWare, and as expected only received an automated e-mail reply so far, I don't except more either, I just tried.
