Which one is better, Nokia N73 or N78?

Before we realize it, Nokia N73 has been on the market for more than two years. In the past two years or so, N73 can be said to be the most popular model under Nokia. Although Nokia later launched models with more novel designs and more powerful functions, it could not replace the status of N73. Although the status of N73 has not been replaced so far, sooner or later N73 will be eliminated one day. In order to fill the gap left after N73 is eliminated, Nokia must launch a model as the successor to N73. The mobile phone officially made its debut at the 2008 Global Mobile Conference held in March this year, it is...N78.
