The worldwide hosted virtual desktop (HVD) market will accelerate through 2013 to reach 49 mln units, up from more than 500,000 units in 2009, according to Gartner. Worldwide HVD revenue will grow from about $1.3 bln to $1.5 bln in 2009, which is less than 1% of the worldwide professional PC market, to $65.7 bln in 2013, which will be equal to more than 40% of the worldwide professional PC market.
