A lot of the article is fluff, but this part describes the onboarding process the author liked:

After installation, you'll experience several pieces of the puzzle that contribute to stillOS's claim. First, you're informed that an update is happening in the background, and you can continue without interruption. That should help give users a sense of reliability.

There's nothing to see here; just an atomic update.

Next comes the ability to select which applications to install. This goes beyond the typical web browser and office suite. With stillOS onboarding, you can select apps to install from several categories, such as web browsers, productivity, music listening, gaming, creative work, utilities, and LLMs. Expand each category and select any/all apps you want to install. You're not limited to a single app in each category. For example, you can select as many web browsers as you want, or as many office suites. 

You can install apps from all of these categories.

Take, for instance, the productivity section, which allows you to install things like OnlyOffice, LibreOffice, Planify, Todoist, Trello, monday.com, ClickUp, and HubSpot. 

You want productivity, you got it.

After you complete that process, you can choose to open the First Steps app immediately.

stillOS is easily customizable

Another thing that makes stillOS consumer-ready is the First Steps app, which is similar to what some other distros might call a Welcome app, only it includes quite a bit more. With First Steps, you can:

• Install apps
• Configure displays
• Customize the layout and extensions
• Manage online accounts
• Add Bluetooth devices
• Configure printers
• Sign up for the stillHQ forums

For instance, click Launch for "Customize the layouts and extensions," and you can select from several pre-configured layouts, including ones that resemble different Windows releases, a MacOS option, a GNOME layout, one that resembles elementaryOS, a layout that looks like ChromeOS, and more. 

After this, he describes some annoying bugs, and recommends that the distribution work on its polish before it can be ready for the masses.
