Tablets change our expectations of software

PC software, over time, has grown in size and complexity. For any product, any version had more features (and used more memory) than the previous version.

Microsoft Windows almost made such a change. The marketing materials for Windows offered many things; one of them was simplicity. Windows programs would be "easy to use", so easy that they would be "intuitive".

While software under Windows become more consistent (identical commands to open and save files) and programs could share data (via the clipboard), they were not simpler. The steady march of "more features" continued. Today, Microsoft Word and Microsoft Excel are the standards for word processing and spreadsheets, and both are bulging with features, menus, add-ins, and sophisticated scripting. Competing PC software duplicates all of those features.

Software for tablets is following a different model.

The products for tablets released by Apple, Google, and even Microsoft are reduced versions of their PC counterparts. Apple's "Pages" is a word processor, but smaller than Microsoft Word. Google's "Drive" (the app formerly called "Docs") is a word processor with fewer features than Microsoft Word, and a spreadsheet with fewer features than Microsoft Excel. Even Microsoft's version of Word and Excel for Windows RT omits certain functions.

I see three drivers of this change:

The tablet interface limits features: Tablets have smaller screens, virtual keyboards, and the software generally has no drop-down menus. It is quite difficult to translate a complex PC program into the tablet environment.

Users want tablet software to be simple: Our relationship with tablets is more intimate than our relationship with PCs. We carry tablets with us, and generally pick the one we want. PCs, in contrast, stay at a fixed location and are assigned to us (especially in the workplace). We accept complexity in PC apps, but we push back against complexity in tablet apps.

Tablets complement PCs: We use tablets and PCs for different tasks and different types of work. Tablets let us consume data and perform specific, structured transactions. We can check the status of our systems, or view updates, or read news. We can bank online or update time-tracking entries with tablet apps. For long-form composition, we still use PCs with their physical keyboards, high-precision mice, and larger screens.

The demands placed upon tablet software is different from the demands placed upon desktop software. (I consider laptop PCs to be portable desktop PCs.) We want desktop PCs for composition; we want tablets for consumption and structured transactions. Those different demands are pushing software in different directions: complex for desktops, simple for tablets.
