Startup Idea: Next-Gen Web Browser and Computer with Built-in Printer

Startup idea to develop a high-performance and secure web browser to address stability issues in existing browsers. The idea also includes the concept of a portable computer with a built-in printer and is designed to optimize media streaming and display, offering long-lasting screen savers for an uninterrupted online work experience.

I am a regular using of a HP desktop computer but wish there were a better web browser that doesn't crashes like firefox and still works fast and a much better operating system the Microsoft internet explorer which slow to load at times depending on internet speed and more secure for users and I desire more secure and safe browser than firefox. Also would like to see a portable computer with a built-in printer if that's possible. And to see a computer better built for consumers to stream, watch videos and shows online better and the screen savers that last longer without cutting in so often while working online.
