To go along with the One (M8), HTC has created the Dot View case.
The perforated Dot View case combined with the full HD display of the One (M8) give users a dot-matrix view of status updates like incoming calls and text messages, time and weather without the need to open to cover. You can also tap on the cover to get a quick status update on calls of text messages that you might have missed.
The Dot View case is cool in retro kind of way but its a pity that the cheap rubbery construction disguises how wonderfully well-build the One (M8) is. Also, it would be good if HTC could incorporate a battery battery pack into the case like the Power Flip case HTC created for the One Max
