Some work quite well. I was impressed enough with the capabilities of the free MyScript Memo app that I purchased the handwriting recognition feature in my copy of Notes Plus for iPad, which uses the MyScript engine. I generally print when I write by hand, by I've read that MyScript apparently works well with (at least some people's) cursive handwriting as well.
PlayON + roku did provide pc to tv streaming capapbilities, and , from what i read , were pretty good. And they did it for some time. But the pricing was higher: $50 for ruko + $100 for playon software.
Google just convinced netflix and others to add the cast button(which is definetly a good idea) , lowered prices and did a lot of marketing. These are things that generally done by big companies.
The Simpsons features the Newton during the episode "Lisa on Ice", where school bully Dolph makes a memo on the device to "Beat up Martin", which the handwriting recognition software mistranslates to "Eat Up Martha".
I see lots of people typing on the iPad screen keyboard. Handwriting recognition? I haven't seen people using an iPad for that.
Just wanted to clarify the processor vendor in the device I bought last year is Telechips and they are from Korea. The larger point I was trying to get across is that all the building blocks are available today (in fact yesterday) but the missing ingredient seems to be software and the visionary who puts the pieces together. In this case it was Google (or an engineer there who spotted the potential) who found the killer app, in the past its been Dyson with his vacuum cleaner, Steve Wozniak with the Apple 1 and more recently Eben Upton with Raspberry Pi. The exciting part is all the parts are readily avaialble for some cool innovations around the "Internet of Things" and we will see the birth of some great companies this decade. Hopefully we will spot them here first at EETimes.com!!
