You know your tablet platform has made it when you've scored a supply deal with an airline, whether it's for the passengers or the staff. Microsoft undoubtedly feels that kind of validation now that Emirates has decided to give Windows 8 PCs a try. The air carrier will eventually outfit all its flights with HP ElitePad 900 slates, each loaded a custom Knowledge Driven Inflight Service (KIS) app, to help crew and customers alike. Attendants will get feedback and a heads-up on what to expect from everyone onboard; passengers will have chances to make their voices heard and upgrade their seat classes on the spot. Only 100 of the tablets will be in use by the end of January, but the 1,000 ElitePads needed for all aircraft should be active before 2013 is over. We just hope the rollout is quick enough to let us splurge on a sleep-friendly seat during a long trip to Dubai.
