The A7-powered iPad 5 expected to be announced next week will accelerate the trend of people using tablets instead of PCs, argues an investment note from Deutsche Bank Equity Research.

We…expect growing [desktop] virtualization and iPad deployments in the enterprise to pressure corporate PC sales through 2014-15…We expect AAPL’s [Apple’s] iPad refresh to include 64 bit architecture, which should enable a greater array of enterprise App development and facilitate greater enterprise penetration over time.

Deutsche Bank had previously forecast that PC shipments would decline by 8 percent in 2013 and 6 percent in 2014, but has now lopped two points of each to predict -10 and -8 percent.

Apple is expected to unveil the new iPad 5 and iPad Mini 2 at a media event on October 15th. With the iPads, OS X Mavericks, the Mac Pro, Haswell-powered MacBook Pros, Haswell Mac Minis and more, the event could be a crowded one.
