Bikepacking - a viable alternative to racks & panniers

Bit of a niche query, but on the off-chance – has anybody here tried taking an ipad mini or similar on a tour to do a bit of work?

I'm daydreaming about getting a bit of a solo trip in this year but im short on holiday days, so am considering doing half a day of riding and half a day of work (marketing nonsense, mostly planning and copywriting).

Hurdles I anticipate are:

• ipad mini not being big enough to really do any work on
  
• me not wanting to do any work and then just not doing it
  
• poor signal in rural france
  
• breaking the ipad due to cramming it into a frame bag/seat pack
