As for "we can still watch it" , well, yeah, kinda. For a while. But I hope that you've noticed how quickly technology is developing now. VHS machines can no longer be bought, to the best of my knowledge. The latest release of the OT was on DVD, but DVD is already an outdated format. DVDs will go the same way, and soon, too. Very soon. Even Blue-ray is on the verge of becoming outdated with HD-TV and Netflix - because who needs to buy a record if you can access your movies in HD directly from the cloud? That possibility is already here.

I've noticed how quickly technology is developing, but unlike VHS, DVD is not an outdated format. You can still go out and buy a DVD player and Blu-Ray players can still play DVDs. And even if you are worried that Star Wars may never again see a release in a newer format, DVDs, unlike VHS tapes, can be inserted into computer drive and copied with relative ease, making it possible for you to convert Star Wars to whatever future format might exist.

And furthermore, like -1 said, there are countless fan preservations on this site of the original trilogy from various sources, most turning out even better than the official DVD release. If you'd like help getting these I can even help you out if you're unsure how to get them.
