I will encourage Sikhs to use computer & internet due to comparitive advantages.
It is easy to search as well as read Gurbani and different versions of viakhia online.
One can listen to Paath, Keertan, Katha anytime 24/7.
Personally, i don't store any files on P.C or Laptop just have bookmarks.
In regards to hand held devices, presentlly i have Nitnem and some Shabads in audio format.
A sevak uploaded Sri Guru Granth Sahib jeeo as well Sri Dasam Granth in reading format on my mobile.
Initially i found it very convenient, the program had various quick search options.
Couple of days went by and i started to experience pain in my body without any reason.
Then by Satguru's grace i realised it is Be-adbi and immediately removed the files.
Therefore will not recommend the use of hand held devices for reading Gurbani, one can never be too careful !
