I have been using an EP 121 since 2010. It has recently developed a sporadic fault which makes it spontaneously close down. l'll post a more detailed description to ask for ideas to fix the fault, but in this thread I'd like to ask for suggestions for a replacement. My main use is for statistical modelling using R. I would want to have at least the processing power of the Asus. I think I would find a smaller screen (such as in the Surface Pro) difficult, and that seems to narrow the field quite a lot. I also use Dragon dictation software, and use the stylus rather than touch. I don't need pressure sensitivity. The Thinkpad Yoga seems to be a possibility, but on the heavy side; and the idea of feeling the keyboard underneath is a bit weird. I've also considered the Sony Tap 11, but the reviews are mixed. I'd be grateful for any suggestions especially from people who have moved on from the EP121. I'm interested in current and upcoming models. Thanks for any input.
