为什么00后用全键盘输入法，90后用九宫格输入法？
智能手机已经全面占领了我们的生活，我们手机中用的最多的软件是什么?我觉得除了某聊天软件之外，最多的就是输入法了。说到输入法，就必须说到输入法的两大阵营：全键盘和九宫格，自智能机诞生之日起，这两大阵营的一直处于竞争态势，至今没有分出胜负。
更有意思的是，前几天我发文征求大家对于输入法的偏好，很多90后(包括我)表示他们更喜欢用九宫格，讨厌全键盘;而更多的00后则表示还是全键盘更符合操作习惯。到底是全键盘好还是九宫格好?今天就来认真地分析一下这件事情。
九宫格
九宫格输入法早功能机时代就已经占领了手机市场，当时手机的尺寸非常小，根本无法将全键盘移植到手机机身上，因此就用九宫格来代替全键盘成为了功能机“御用”的输入法。所以我认为，九宫格之所以能够在功能机时代流行，完全是因为机身太小而妥协的结果。
九宫格的输入法优缺点很明显，优点在于由于按键比较少，而且按键很大，打字速度很快，再配合机械按键的物理回馈，完全可以盲打，完全不会产生误触的问题。而九宫格的缺点在于每个按键对应3-4个英文字母，所以是模糊输入很不精确，可能会出现需要翻好几页才能找到候选词的情况，一定程度上影响了输入效率。
全键盘
全键盘沿用的是电脑键盘的按键布局，因此对于那些习惯并且熟悉电脑按键布局的人来说，手机全键盘的学习成本近乎为0。而且全键盘最大的好处就是一个按键对应一个字母，因此输入非常精确，不会出现九宫格那样翻来覆去找候选词的情况。
全键盘在手机上的缺点也很明显，由于手机屏幕的宽度有限，因此全键盘的每个按键都非常小，对于粗手指来说非常容易误触，每次为了防止不误触，必须瞪大眼睛小心翼翼的输入，容易产生挫败感使用起来比较累。
那么为什么说90后喜欢九宫格，而00后更喜欢全键盘呢?根据大家的讨论来看，最主要的原因是生活环境的差异导致的。因为90后是从小用功能机长大的一批人，他们即便换了智能机也会沿用在功能机上九宫格的习惯;而00后是玩电脑游戏长大的一批人，而且他们根本没用过功能机的九宫格按键，所以更习惯全键盘输入法。
