Hey, I have a really weird conundrum. A while back, when I purchased Windows 8.1 for my desktop, there was a $25 gift cert. to the Windows App store. I've spent a little, but I have no idea what to spend the rest of the money on. Do you have an app that you think is necessary to your Windows 8.1 machine? I have a T100, Venue 8 Pro and a gaming desktop, so if there's anything for any of those devices that you recommend, I would greatly appreciate a suggestion! Thanks!
