Social networking
The home screen on Kin was called Loop, and served as an aggregator for social networking connections from Facebook, Twitter, Windows Live, and MySpace as well as web content from web feeds.
Commentators noted Loop's 15-minute delay for updates, which CNET's Ina Fried described as "odd".[33] PC World argued this delay was at odds with Microsoft's claim that the phone is "always-connected". Users could not adjust this interval,[34] although updates could be manually triggered with an on-screen refresh button, or locking then unlocking the phone. Microsoft cited battery life and immature social networking APIs as reasons for the delay; Engadget speculated that Microsoft may have been using the delayed messaging to encourage Verizon to offer lower-priced data plans, which would be attractive to the platform's teenage target audience.[35]
Kin did not support uploading photos or videos to Twitter. Retweets, direct messages, viewing single person updates, and opening Twitter links from the Loop were also not supported.[34]
Spot
Spot was a feature that allowed users to add an e-mail address or telephone number to an SMS or MMS, or to attach content (e.g., text, URLs or photos) to emails.[34]
The Spot was represented as an omnipresent colored dot near the bottom center of the screen. To add an address field, the user dragged a recipient's photo to the Spot, then clicked on the Spot, opening a page that allowed the user to create a new email, SMS or MMS.[34]
The Spot could also be used to set up e-mail attachments, by the user dragging the content to the Spot, then dragged the recipient's photo to the Spot, after which an email could be sent containing those attachments.[34] However, Kin did not support attachments to non-e-mail media such as MMS and could not be used to send content to social media sites.[34]
Cloud storage
Content from the Kin phone, such as photos, videos and messages, was automatically synchronized to a cloud service called Kin Studio, and would then be accessible via a browser on other devices. The Kin Studio website was written in Silverlight and its appearance was similar to the Kin UI, even including a Spot for sharing content.[36] Kin Studio was shut down in January 2011.
Camera
The Kin ONE had a five-megapixel camera with standard-definition video recording capabilities. The Kin TWO included an eight-megapixel camera with 720p video recording. Photos were automatically geocoded on the original phones, a feature disabled on the "m" phones.[37] There was no photo editing software for Kin.[38]
For media, Kin devices synced with Zune desktop software. In addition, the phones were compatible with Zune Pass. Much like contemporaneous Zune devices, Kin phones could also stream music over a WiFi connection in addition to 3G on the carrier's network.[39] For Mac users, Microsoft, in collaboration with Mark/Space, provided a media syncing tool that pulled audio and video files from iTunes and photos from iPhoto.[36] Kin did not support playing video from sites such as YouTube or Hulu, although the devices could watch YouTube videos from the browser through WiFi or 3G.
Applications
Kin had no app store and no third-party apps could be installed on the phones. PC World described this as "baffling". Further, the web browser did not support Flash web applications,[40] and there were no games for the phones.[40] Microsoft had stated their intention to eventually merge the Kin and Windows Phone platforms, with downloadable apps then being available for the combined platform.
Missing features
Reviewers highlighted a number of notable omissions from Kin's initial feature set:[41]
- Contact lists could only be copied from another phone by Verizon store employees. There was no way for the consumer to do this by any known means (over the air, via a memory or SIM card, wirelessly via Bluetooth and vCard, or via direct USB cable connection).
- Kin had no calendar or appointment application,[42] nor any ability to sync with Outlook calendar or Google Calendar.[43] Some commentators suggested that a social phone should be able to share a social events calendar.[43]
- Kin was unable to Instant Message
Network charges
In the United States, cellular telephone provider Verizon Wireless sold the Kin phones with a voice plan starting at $39.99 per month. An optional Zune Pass cost $14.99 per month for music access.[45]
After the kin.com website was discontinued in January 2011, the original Kin ONE and Kin TWO did not require a data plan, although the optional Zune Pass was still available.
Relationship to Windows Phone
The Microsoft Kin has been described as a "close cousin" to Windows Phone,[46] with shared user interface characteristics. According to Microsoft, "Both KIN and Windows Phone share common OS components, software and services. We will seek to align around a single platform for both products as well as consistent hardware specifications."[46]
Microsoft said that the underlying fundamentals of Kin and Windows Phone were held together by similar core technologies. Both operating systems ran the same Silverlight platform,[46] with Microsoft's stated intention being to eventually merge Windows Phone with Kin.[47]
