- 只能在网页上面使用，qq上面没法用啊，这是一个很大的限制。
- 不支持tab键翻页用部首定字。
- 目前感觉最不方便的就是这个,不过我可以用网页版的webqq.但是部首定字我还是需要的.
- 输入的准确性没那么重要吧,我感觉单机版的搜狗输入法准确性已经很高了.
-
对云输入法的一些建议：
- 根据用户的上下文选择目标文库，比如说 我前面输入了孙子兵法的内容，那么紧接着你搜狗输入法就要考虑把孙子兵法里边的句子有线呈现给用户。优先不是有线。
- 长句输入的时候中间错了一个词，要能够快速定位。最好设置一些快捷键能够直接跳到中间。当然还有智能纠错，我想这些应该是已经有的。
- 做一下桌面程序也能通用云输入法的一个壳.
- 最后，在这里为搜狗推广一下：
猛击这里启动搜狗云输入法,无需安装!
