Apple's iPhone 6 and 6 Plus are the first Apple mobile devices to come equipped with 802.11ac Wi-Fi, which supports much faster data throughput speeds. 802.11ac Wi-Fi is able to offer connection speeds that are up to three times faster than existing 802.11n networks.
iClarified has created a new video that compares the Wi-Fi speeds of the iPhone 6 Plus, which supports 802.11ac, to the iPhone 5s, which supports 802.11n, when connected to an AirPort Extreme. The site also created a custom app for the test.
Both devices were freshly restored to iOS 8.0 and connected to the 2013 Apple AirPort Extreme. The router was placed 1.5 metres away from the smartphones and each iPhone was connected to the AirPort Extreme using a 5GHz-only network. No other devices were connected to the wireless network at the time of the test and the downloads were performed at separate times. We cut them together for comparison.
As expected, the iPhone 6 Plus sees much faster connection speeds that reach 278.5 Mbps, while the iPhone 5s tops out at approximately 101.1 Mbps. While speeds are improved in this test, the actual speeds that users see in the real world will vary based on connection strength and other factors, as an actual ISP connection is generally the limiting factor for speeds when connecting to the Internet. When an 802.11ac Wi-Fi network is available, however, iPhone 6 and 6 Plus users should see significant speed improvements.
Along with 802.11ac Wi-Fi, the iPhone 6 and 6 Plus offer several other connectivity improvements, including faster LTE with support for LTE Advanced and voice over LTE, which enables higher-quality phone calls. The iPhone 6 also supports calls over Wi-Fi, for access to high-quality voice connections even in areas where cellular connection is poor.

Its really not, you won't see any applicable difference in real world scenarios.
ISP connection is not the only use for wi-fi, especially with all the OS X / iOS continuity features that allow devices to work together. So .ac will be very useful.
Not really, because your Internet connection is likely far below the 275Mbps that your WiFi connection can handle. It's really only useful for file transfer within the network, and how often do you do that to/from your iPhone?
