Why doing a mobile version ?
As mobile device gains in cpu and memory mobile browser gets more powerful and a normal web page viewable on mobile device. With some smart browsers or transcoding service a normal web page can even be somehow formatted to fit mobile device.
Three times in a short time span I have been asked why do we still develop a mobile version of our blogs since there will be a time where anyway any web page will be readable on a mobile device.
To those I just give this answer (one amongst a few):
More than 15 years the World Wide Web exists and we still have to handle server side the various browsers. There are only 3 or 4 of them out there while there are over 4000 (growing every day) mobile devices!
