????你正坐在咖啡館里用平板電腦瀏覽新聞，過了幾分鐘，和手頭項目有關的一些想法突然躍入腦海。換作從前，你可能就會把這些想法匆匆寫在餐巾紙上，然后再塞進口袋。或者你可能會立馬給自己發封郵件。這兩種辦法其實都不怎么方便。

????現在，層出不窮的各類軟件正在試圖解決這個問題，幫助人們隨時記錄靈感。它們讓使用電腦或移動設備的用戶有了保存筆記、鏈接和照片的專屬領地。本周，谷歌（Google）推出了Keep，借此也加入了這個原本已經擁擠不堪的領域，而谷歌這么做明顯是受到了對手的啟發。谷歌的一舉一動肯定都經過深思熟慮，因為這項服務背后是個鼎鼎大名的企業，還能觸達數以億計的用戶。

????現在的筆記服務數不勝數，所以要說誰是其中的最出色的一個還真是困難。考慮到這些軟件各自的性能、設計和兼容性，它們都既有優點也有缺點。各家服務的差異主要體現在細節上。

In an earlier era, you'd probably jot the ideas down on a napkin and stuff it in your pocket. Or maybe you'd send a quick email to yourself. Neither option is particularly convenient.

????Today, a number of online services are trying to solve the problem of note taking on the fly. They give people using a computer or mobile device a central place to save notes, links and photos. This week, Google joined the already crowded field by introducing Keep, a service that is clearly inspired by its rivals. Google's effort is inevitably a serious one, if only because it has such big name behind it and access to hundreds of millions of existing users.

????Given the number of note taking services available, figuring out which one is best can be difficult. They all have strengths and weaknesses based on their features, design and compatibility. The differences between services are in the details.

????Can you use your voice to create notes instead of having to go to the trouble of typing them? Is an app available on Android devices? How much data can you upload per month without having to pay?
