Question

Iron

TK:
Choose a device for recording lectures, which should have a trace. functionality:

• Sufficient autonomy (6-7 hours of work in 3G / Wi-Fi mode)
  
• Light weight of the device
  
• Convenient text entry
  
• Support for any online note service (Evernote/OneNote, etc.)
  

The choice fell on:

• Microsoft Surface Pro 3 + keyboard case
  
• iPad + keyboard case
  
• ASUS EeeBook X205TA
  
• Macbook Air 11`
  
• Lenovo Yoga 3 11`.
  

Who used these devices share your experience.
Or what typing device do you use and why?

Answer 1

The answer is obvious - Macbook. Retina screen and weight less than a kilogram, 12 inches, comfortable keyboard and touchpad. 9 hours of work.
PS Recording lectures without a stylus is unrealistic, forget about this idea. Or look for gadgets with a stylus, the dude looked around on Habré (I couldn’t find it)

Answer 2

You will not find if you do not soften the requirements. You would also add handwriting recognition there, to complete the picture)
You need a stylus to write. Those. it's either tablets on android / ios, or on Windows.
On android, Galaxy Note Pro 12.2 would be suitable for such purposes, on Windows - anything with a stylus included, for example Surface. At one time I used for similar purposes (minutes of meetings) Hp Compaq TC1100.
In fact, autonomy will be the most problematic (especially in 3g mode, where the battery will melt before our eyes), and convenient text input. On all devices that I have encountered, lags and (occasionally, but more often than I would like, occurring; non-critical, but nevertheless unpleasant) positioning micro-glitches make writing unintuitive. Cognitive dissonance makes itself felt.
And also any oversight (accidentally poked the wrong icon, accidentally turned it off, etc.) causes delays, and the principle "and let the whole world wait" when recording lectures is not very applicable. As a result, get stress and gaps in the material.
IMHO it's easier to write on some normal notepad , and then scan / photograph, it will be more efficient.
