I think that all companies should be advertising on some sort of tablet device. Its the new hit technology today. If your not then your behind the times and need to seriously fire your marketing team. Its almost like if you dont have a facebook, are you in a cave? Some companies may not have the money to fund some of these new trends. some may think why spend the time and money now when in a year there is going to be something even better. who knows but i think they should invest in advertising using these devices now
