Can you spot the problem? This isn’t exactly an epic fail, nor is it particularly or devastatingly terrible, but I do think that mobile devices do need to work properly, and clearly this is a bug. This is a HTC Desire, but the same bug is replicable on the HTC Desire HD. While this isn’t a reason not to buy an android phone, I choose to use it as an example to make myself feel better about living inside the Apple Reality Distortion field. Sure, the iPhone might be communist, but the streets are clean and the trains run on time.

UPDATE
It turns out that this is a bug with the HTC Basic Calculator, and not a bug with the device itself (as verified by testing the same math on another calculator app on the same phone) but it’s still as funny as hell.
