We need an open source hardware device running a truly open source OS. That would be really nice.
EDIT: Even if we don't have open source hardware, what would be great is having the ability to buy modular parts to build up our own devices. This used to be common practice with desktops, but got totally killed since laptops took over.
If I had an extra life, that would be my startup.
Probably hardware and software will continue to be locked down (or in Android's case, released to open-source many many months after official release), but we'll be rescued by the web the same way we were in the PC era.
And to your other point... closed nature has its upsides too. Look at gaming consoles, they work quite well despite being crazy controlled. And Apple never wanted to dominate the whole phone market... if you remember the iPhone introduction, they didn't want to own the whole market. They defined its own category, basically :)
It is precisely because it was so good that it was such a threat to the technology landscape. We could easily have descended into a windows like era of domination by one company, but this time with the company having complete control over every layer - hardware, software, even content. However we didn't, partly thanks to strategic mistakes that Jobs made (we could have a whole discussion about what those were but I think it would be counterproductive wrt this thread).
I think almost like a natural ecosystem the software world needs both open and closed systems in balance. Each one moves us forward in different ways at different times. It is when they get out of balance that we get stuck (the "windows" era being a good example).
For instance I recently unsubscribed to Groupon emails. After doing so Groupon pointed me to a page to watch a tongue and cheek video to get me to change my mind.
I hate getting spam emails and I was very eager to banish any further Groupons (signed up by mistake). There tongue and cheek video was very ineffective for me. I did think it was unique, interesting and something worth sharing. But, since I felt negatively towards it the title of my submission was "Worst Email Unsubscibe Page?". Because that is how I felt about it but still wondered what others thought.
For whatever reason because I chose a negative title the submission was flamed - http://news.ycombinator.com/item?id=2928041
Again that is how I felt time of writing the title because it was un-effective for me, but wondered what others thought about it.
Ive been reading HN since May '07 (various accounts) so Im not a noob. Maybe Im someone who thinks differently at times then others here?
