Ask HN: What's your best startup idea that you're not going to pursue?

The problem is that you need to reproduce the local Excel environment, or the local video rendering environment, in the cloud. That is either something you do on a per-vertical basis or perhaps with some very advanced system administration tricks.

Also, video is probably not a good candidate, because it's data heavy and relatively CPU light. The good candidates for cloud offloading are lots of computation on small data, which does not fit the class of things that most people do on their desktops these days.

- Tablets for seniors: when the elderly population sees an iPad ad, they're not captivated or entranced; they're intimidated and disappointed that they're left behind by technology. I envision the "jitterbug for tablets" -- built on Android with big, tactile buttons; a 'never get lost, take me home' feature; remotely controlled functionality (IE turn on/off apps); etc. They wouldn't use much bandwidth, so you could build 3G right into the device and charge a significant monthly premium -- after all, it's a dramatic quality-of-life improvement for someone sitting in a retirement home.

GE and a few other companies are doing similar projects, but no one is really executing all that well IMO. Problems: would be super hard to get off the ground / defend, and the market is becoming increasingly obsolete.

I've made a naive summarizer that seems to get the job done for the summaries part: http://breue.com/summarizer

I'm just not sure what the final product would look like or if there would be enough of a reason for people to prefer it over Pocket.
