In my opinion there is a big difference in learning Chinese based on textbook/classroom learning to day-to-day interaction to personalized lessons. I think it depends on your level, commitment level, purpose of learning (Do you only need basic day-to-day spoken language skills? professional language both writing & spoken? be able to write? Etc,.)
Based on my 5 years of learning Chinese now, my needs have changed as with my methods. I have to agree technology doesn’t hurt when it comes to efficiency & 24/7 access you have where as a textbook based learning is so limited in not just time but rigidity in structure and often times being far fetched from average person’s day to day experience living/ working in China.
