Machinarium & IPAD

I have been meaning to play Machinarium for a long time, but simply didn't get around to it. This Christmas I was given an IPAD as a gift and downloaded Machinarium for a super-low price ($2.00). This leads to my question: is the game I'm playing on my IPAD the same game I'd have played on my PC? More generally, are there significant differences between IPAD games and PC games?

The author compares the iPad version with the Mac version (which would be similar to the PC version). He also compares the current version for iPad 2 with the earlier iPad version that ran on the iPad 1.

The developers had several sales where they sold Machinarium for $5 for the PC in recent years. You probably have the same game. Hope you enjoy it as much as I did
