Non-removable Apple Batteries. Why? | by Sander Nizni
Introduction: Permanent vs. Removable Batteries
Is usability of portable devices better when their batteries can be removed on the fly? Definitely. But there are many schools of thought on this topic – both regarding Apple’s products specifically and regarding product strategy in general. There are five reasons device manufacturers do this, and there are three why they shouldn’t. But this is not a typical numbers game: I feel in this case 3>5. Let’s explore the pros and the cons of device usability in the context of fixed – or permanent – batteries in portable devices.

Wireframes and prototypes – as well as software used for wireframing and prototyping – make the process of creating an app, a website or any software or hardware product notably easier – by simplifying the product and allowing all involved in its development to focus on the product’s functions and user interactivity. Everyone in the production team – from stakeholders and information architects to project managers and quality assurance personnel – needs to understand how an application or website will work and what it is intended to do. For that purpose, wireframing and prototyping are not synonyms, technically speaking. Let’s look at their differences and similarities.
Through my many years of working with screens – computer displays, television sets and proprietary video hardware – of varying sizes and intended uses, I find one factor to have a much bigger cognitive role than the innocent context of this usability topic may suggest – aspect ratios. Over 20% of the world is using electronic displays or TV’s with wrong aspect ratio settings, and it turns out that this has deep physiological and psychological effects that affect the users, the product manufacturers and everyone in the advertising sector. Should anyone care about this usability problem? I have done the research to find a few interesting answers.

I don’t love guns, but sometimes a gun can help tell a story. So, this post is a bit odd but is fun and educational. All those who have worked with me in software teams have heard me say, “Let’s make this feature work like a revolver!” This expression is not my own – I “inherited” it from a good friend who is a front-end developer, but it represents a principle in product design that I follow. And believe it or not, it all started with cars and revolvers and LSD… as in
