So, I have the iCade, the first edition from Think Geek, and was looking into getting an iPad 1st gen to load up some arcade action. is the first edition still worth purchasing? I have the Atari Greatest hits, and the Midway arcade pack as well. Im thinking the batteries on these have to be at the end of their life cycle. what about replacements? I want the original, as it offers the best fit for the original version of the iCade cabinet. It also has a big enough screen border to allow for a custom Arcade Skin to be applied to complete the look...
