IS TECNO THE MOST USED PHONE NOW?

While recieving lectures at a hall 2day at school, I just checked all the extension boxes connected to on anoda and was a little bit suprised to see the large number of tecno phones there. Tecno has improved a lot on their phone by even introducing the HD series. Instead of getting a nokia fone for 12k, You can use the money to purchase two quality tecno phones. Is tecno the most used phone. Either as 1st phone or a backup phone for your BB?
