Sales.
The HTC Touch sold 1 million units by October 2007 and HTC expected to sell 1.5 to 1.8 million units by the end of 2007.
Over 1 million HTC Touch Diamonds were shipped in 6 weeks, compared to the HTC Touch, which took 5 months to reach the same milestone. HTC consequently raised its sales projection for 2008 from 2 to 3 million units.
When the HTC HD2 was launched in the UK, Vodafone quickly sold all of its stock and developed a backlog of orders, and O2 delayed putting the HD2 on its website so that it could fulfil all orders. Similarly, in the US, the HTC HD2 sold out in most T-Mobile stores within 4 hours and T-Mobile struggled to keep it in stock for several weeks.
