今年总共有85款平板电脑新产品在美国国际消费类电子产品展览会（Consumer Electronics Show）亮相，其中多数产品运行的是谷歌Android操作系统。通过本次调查可以发现，开发商对这些平板电脑兴趣大增的原因有三点：1.价格优势（57%受访者认为这是最重要因素）；2.最小化的平台分散性（看中这一点的受访者比例为49%）；3.全新平板电脑操作系统Android Honeycomb OS的性能（有33%的开发商很关注这一点）。
Windows Phone 7的支持率也有了8个百分点的小幅度增长，目前已达到36%，不少开发商称他们选择WP7是因为该平台变身效果明显，用户界面也有了较大改观。
调查还显示，开发商对网络电视应用商店的兴趣开始骤减。由于谷歌最近推迟了Google TV项目，不少开发商对该平台的支持率也下跌至33%，同比下降了11个百分点；Apple TV的情况也难免如此，目前支持率为30%，下降了10个百分点。Yahoo TV、Boxee和Roku等网络电视的支持率更是微乎其微。
Developers Report Increased Interest in Android, Tablets for 2011
The average developer is now building for four different devices, a joint survey from app development firm Appcelerator and analyst firm IDC has revealed. Of those multiple devices, building apps for Android tablets is now a consideration for many developers, with 74% of the 2,000 developers surveyed responding that they are “very interested” in developing for Android tablets.
But the interest in Android tablets – up 12 points in the past three months – is indicative of a growing interest in tablets across the board, says Appcelerator. iPad interest also rose 3 points to reach 87% and BlackBerry PlayBook interest doubled from 16% to 28% during the same time period.
Android Development Takes Off
There were 85 new tablets introduced at this year’s Consumer Electronics Show (CES 2011), the majority of which were running some version of Google’s Android mobile operating system. According to the developers surveyed, the success of these tablets will be dependent on three factors: price (57% say this is the most important factor), minimized fragmentation (49%) and the capabilities of the new tablet-centric Android Honeycomb OS (33%).
Meanwhile, as Android tablet interest grew (now at 74%, as mentioned above), Android phone interest grew as well. Today, 87% of mobile developers said they were “very interested” in Android phone development, a response that rose 5 points, edging out iPad and coming within 5 points of iPhone (92%).
And interest in Amazon’s new Android App Store is showing a surge of interest, too. 37% of developers are interested in distributing apps via Amazon, as compared with 13% interested in Verizon’s VCAST app store and 9% interested in third-party app store GetJar. 82% are interested in distributing apps via Google’s official Android Market.
iPhone Still Tops, Other Platforms See Smaller Changes
However, iPhone is still the number one priority. Says Appcelerator, the question developers are now asking themselves after launching on iPhone is this: “do I go Android or iPad?”
Another mobile platform seeing a minor increase in interest is Windows Phone 7, up 8 points to 36% of developers indicating strong interest. The respondents said it was the OS’s revamped and improved user interface that drew them in.
Connected TV App Development Interest Declines
Outside the mobile ecosystem, there was little interest in developing apps for Connected TVs (Internet-connected TVs with accompany app stores). Thanks to Google’s recent pull back on its Google TV plans, developer interest also dropped. It’s now down 11 points to 33%. Apple TV also dropped 10 points to 30%. Interest in Connected TV alternatives like Yahoo TV, Boxee and Roku was also minimal.
Mobile App Strategies
The survey also took a look at where both enterprise and consumer development efforts were in terms of mobile app strategy. Last year, many survey respondents (43%) said they were in an exploratory phase, and typically only offered an app or two, one of which was usually for the iPhone.
Now, 55% of respondents say they’re in the “acceleration” phase of their overall mobile app strategy. On average, respondents say they plan on developing 6.5 apps this year, up 282% from last year.
Businesses in particular are taking a multi-platform approach, the survey found. And, on average, the survey respondents said they are now building for 4 devices this year: typically, iPhone, iPad, Android phone and Android tablet.
Their apps will often be cloud-connected (87%, up from 64% last year). The apps will also be personalized and contextual, offering integration with both social and location services.
As noted by earlier reports, the survey also confirmed the trend of moving away from app sales as the primary revenue-generating outlet with more focus on alternative income sources like in-app purchasing and advertising.（source:readwriteweb）
