Gmail tmned five years old this week．It's somewhat amazing to think we've only had it since 2004; Gmail changed the webmail game forever by offering features we now take for granted: a streamlined interface （界面]） , powerful search, pioneering use ofAjax and a then-huge 1 GB of mailbox space．“You'll never need to delete another message " was how Google described it at the time．
Back then, I was still making do with Hotmail．But its clumsy interface and tiny amount of storage space made the decision to move on an easy one．Getting an account made all the difference in the world to my email experience．Suddenly I was freed from having to delete emails every few days to make space in my mailbox．And the app（application） was smooth and responsive, like a desktop client （客户端程序）—and pretty fast in comparison to Hotmail．" Conversation view" and using labels instead of folders took a little getting used to, but in all Gmail felt far more professional and made me much more productive．
Gmail is a favorite app of ours ever on WebWorkerDaily, and with good reason．It's still the best webmail client for web workers as it lets us access our email whenever and wherever we need to, on any device, with minimum effort．And Google hasn't spent the five years sitting on its Gmail success, either, but has introduced improvements to the service that include Gmail Tasks, chat, video chat and voice chat, combined with Google Calendar and Docs, Google Apps for Domains, and, of course, even more storage．We've recently covered the many features found in Gmail Labs: a way to "undo" seat messages, using canned responses for smart autoresponders, offline support using Gears and how to customize the way you．view your mailbox using multiple inboxes．
