Seems like it could be a useful tiny computer for travel etc., provided you could live with the power, memory and storage limits. Could avoid carrying a laptop if you could arrange for a keyboard/monitor/mouse at the places you go to, e.g. trainings, conferences, client visits, etc.

Price starts from as low as $55 and goes up to $120 or more. Some models support Windows and some Linux.

Haven't investigated more so don't know if it has any issues.

Thanks in advance for all answers.
