手機硬體的重要性 - Android

看到大家常常在嫌HTC的手機CPU很差，硬體不好。
但是身為一個軟體工程師外加多年的android使用者。
我後來發現，手機目前還不需要有所為硬體的迷思。
舉兩個例子
我之前是用X10 我弟是用desire，我記得沒錯的話，兩個是同CPU
結果desire跑遊戲硬是比X10流暢
我曾經賣一支acer 犀利機給我朋友
犀利機介紹：http://www.sogi.com.tw/Product/productInfo.aspx?pno=7660
結果我朋友嫌他動作不流暢，改去買desire
犀利機的硬體規格比desire高一個世代....不過手機的一個世代差不多就是3～6個月
所以後來有一陣子朋友要我推手機我都推desire，雖然desire最近有朋友跟我反應
儲存記憶體那邊有問題。不過那也是快兩年前的手機了，現在才因為空間不足出問題，
也算能稱了。
再來，CPU好，真的會對手機有正面的幫助嗎？ 這是當然的，但是韌體太差所造成的後果
比CPU好壞更為致命。
以軟體工程師而言，一個真正好軟體，是在個個手機上都能正常執行，才能大賣。
今天並不是每個人都拿旗艦機XL或S2，也是有人拿wirdfire的
所以要做到相容性就是一個很重要的課題，你會發現賣的很好的軟體，在低階機上，往往
也可以跑的很順。這是因為工程師有注重軟體的校調，會寫軟體的人多，但會寫好軟體
的人少。根據市場機制，留下來的就是那些好軟體。
所以單就去比較硬體的數字或者是比bencemark跑出來的數字，對手機的好壞幾乎沒差
除非你是想要在手機上面跑photoshop或是build code.
另外就是耗電量，這是一個有趣的問題，耗電量居然會跟手機裡面裝的軟體有關。
如果你今天裝了一個爛軟體：就算你都沒開啟過他。你手機一樣會耗電快速。
這是因為android的系統設計裡面，給工程師有一個非常方便的功能叫做service
他可以幫助你在background做其他的事，可以作運算，做網路讀取。
這個功能非常耗電，所以不用的時候最好關閉，像apple ios就沒這個功能所以相對省電。
但是關閉service的這個行為對工程師而言是一個麻煩又難搞的工作。
所以market上的軟體大多沒有關閉service的動作
換句話說，今天你只要裝了一個爛軟體，你都手機就會莫名其妙狂耗電。
所以結論是
1. android的選擇，最好的就是走到店裡真的拿起來玩一玩，用一些你會用的的軟體，
試試看跑的順不順，硬體規格請當作參考。
對我而言，硬體最重要的有以下幾點
1. 外型順不順眼
2. 音樂好不好聽
3. 螢幕看起來舒不舒服
4. 相機功能好不好
2. android的耗電量和效能目前最直接的關係是軟體，所以請遠離爛軟體，market上
真的很多軟體有毒，請小心服用，這個毒不見得會把系統搞到crash但是會把你搞到
