Re: MTK
I don't know much about programming or using Java on a Linux like OS or MTK but apparently there are many phones in China's Shenzhen factories now made using this 'mold'. The end result is you can get a phone that has GSM, Bluetooth 2.0, Wifi, plays MP3 (or ring tones changeable), plays MP4 videos etc.; on a 3.5" touch screen, 2 megapixels camera and even runs Java applets or games. All this in a phone which is roughly USD$85 at wholesale prices. This means a thousand handsets will costs roughly only USD$8,500 dollars. Unlike a few years ago, this small MOQ is very do-able as the technology matures and many factories can churn out the same specification phones.
All I am saying is that when the iPhone version of Pleco is finally stable, Mike could look into the possibility of providing both the hardware and software, sort of like the way many electronic dictionaries (for the English language learning market) are sold in China/Hong Kong. This way the Pleco dictionary series will become that much more affordable to a wider range of Chinese language learning students, and the performance of the Pleco program can also be standardized on to a 'fixed' hardware. There are plenty of second language learners of Chinese who live in places like the Philippines, Thailand especially or Malaysia etc.. who can't afford the current WM+pleco, or iphone+pleco combination. A pleco plus purpose-built hardware phone would be much more affordable to many more students.
I am not sure what (Taiwan made)MTK is but I think it won't take long for a techkie to find out how difficult or easy it is to program on that or similar OSes. I think the "Westerners" or adult learning Chinese as a second language will still continue to expand in the coming decades. I know personally the South-East Asian market or ASEAN market for Chinese language learning is huge. A thousand purpose-built handsets sounds like a lot, but its less than the number of people studying Chinese as a second language in Hong Kong. And after all that, there will still be people who can afford and want the Pleco in a WinMo or iPhone. So what I am suggesting is 'expanding' the overall market.
