To add to that, they already have an engineering office in Tempe.
I suspect both Phoenix and Tempe will be strong contenders.
Positives: - Affordable housing - Affordable corporate real estate - Construction boom in both cities - Local governments interested in wooing corporations
Downsides: - No deep CS university pipeline - No strong tech presence, complicating hiring - Will need to offer incentives to get people to move - Public transport is lacking
