Beyond the tiles, there are a few other new features in Mango that I really enjoy. Tombstoning and basic multitasking support are implemented quite well. Enabled apps close in a frozen state, and holding down the back button for a second quickly brings up the task switcher UI. Transition animations are subtle but appreciated, and jumping between apps is lightning fast.
I also like that Mango brings Wi-Fi tethering to Windows Phones. The Internet Sharing service on the Titan is buried in the system settings in Windows Phone, rather than being granted a dedicated app that I might be able to pin to the home screen, but I still appreciated having one less device to carry while testing the Titan.
Wi-Fi tethering is available on a number of smartphones these days, but I typically find it unusable due to the inevitable battery drain. The Titan's 1,600 mAh battery held up nicely even after about 30 minutes of Internet Sharing, and Mango includes a nifty feature: if no devices connect to the phone after a few minutes, tethering is automatically turned off. Also, if you're tethered and then you disconnect all devices from the phone, Internet Sharing will automatically turn off after a few idle minutes. It's one less thing to worry about.
