Yes! Although the OS is still considered “beta”, it is reasonably stable and can be used to perform most daily tasks such as browsing the web writing and reading e-mails, or listening to music and watching videos. We strongly recommend that you make backups of your personal files regularly.
Can Haiku connect to the Internet?
Yes! We reuse network drivers from FreeBSD, so most network adapters will work on Haiku out of the box. Haiku includes an e-mail client and a web browser, and you can install other network-enabled applications.
Would like to hear more about your Haiku experience. Is it a decent daily driver?
