New vs Great (IM 630)

The biggest challenge of today's world is to chose between "new" and "great". It's always a challenge to chose between new technology and the great technology. It depends on individual's likes and dislikes. While choosing a book to read, what do you prefer? A book with a new big thing or a proven great classics? While choosing a technology, what do yo prefer? A new tech or a great practical tech? This is always a challenge. I always prefer "great" over "new".
