Nah, sometimes I just want to check the current temperature. A persistent problem with LCD-powered devices is that because of power consumption or general visual obnoxiousness their screens need to be kept off until use, but there&#x27;s always a time lag.<p>One of the more glaring problems with smart devices - smart watches especially - is that they have have a slight pause before they realize they&#x27;re being used and activates. An always-on device doesn&#x27;t have this problem and can be immediately used without delay.<p>By themselves they&#x27;re not huge issues, but as you own more and more such devices it becomes really annoying to be surrounded by &quot;smart&quot; inanimate objects that constantly make you wait - even for a brief moment - before they are usable, and in that way they seem much less pleasant than the dumb objects they replaced.<p>Imagine having to rest a pen on paper for 500ms before you can begin writing, every time.
