Haptics, it's always the next big thing
Put some money on Immersion a few years back, was convinced (still am) that haptics are going to be massive, and that every single phone, tablet, thing is going to have them in.
But boy has the uptake been laggardly. The share price has gone nowhere. I've got a Nexus S, and the haptics are rudimentary at best - companies only seem to license the lowest of the low in terms of haptics, Immersion have much better tech in their labs, but it never makes it into a product.
Hiwave are so cheap though, the company is only worth £6.5M. That is absolutely nothing to any mobile phone manufacturer, so if the tech really is good, then it's probably worth a punt as a takeover target. I'm not putting any more into haptics though.
