I know the two are very old models. But i want to get one as my sub tablet. I don't want too much functions, too high speed. Just good tablet function. And, i just want to check how much different the two is. 1. If 'speed/screen resolution/pen input' is similar, I will choose cheap one. 2. If LE1600 is considerably slow or screen is too dark or much much worse wholly, I will choose expensive one. Is there any big difference on the two? What's your advice? thanks a lot.
