I'm the wrong guy for these toys. The 5285, Surface, etc. I've tried coding and in general working on spreadsheets on these and the feel just wasn't right. The keyboards aren't as solid as a real laptop and for a program such as FE I think that should be a deal-breaker.
When I used a convertible in the FE program it was an old IBM flip laptop that had an awesome keyboard. These removable ones just don't do it for me. That being said; I have never owned one of these long enough to make a very accurate and unbiased assessment, so best ask someone else.
Two other small points:
1. I see the 5285 is a "U" processor. Does that still stand for "Ultra low voltage"? If so you might want to take care, those tend not to preform so well in heavy CPU applications (gaming, programming, etc.)
2. I like laptops to be customizable so I can upgrade the ram, HD, etc. I doubt if these tablet machines are. I don't know for sure but it is something you might want to check.
P.S. If you are going for a writing tablet you might want to check the pen technology. Back when I followed those tables, Wacom was king and N-Trig was a wannabe. N-Trig was the Surface technology and it was less than desirable to write with. I had many Wacom tables and loved them all.
