Push Email Definition

Push email utilizes a mail delivery system with real-time capability to “push” email through to the client as soon as it arrives, rather than requiring the client to poll and collect or pull mail manually. With a push email smartphone, for example, the client’s mailbox is constantly updated with arriving email without user intervention. Smartphones announce new mail arrival with an alert.

Push email differs from conventional email systems that are “pull” oriented. Usually, when email is sent, it arrives at the recipient’s Internet Service Provider’s (ISP’s) mail server, where it is held for collection. It might instead arrive at a website server, if the email is Web-based. Either way, email remains on the mail server until the recipient uses an emailprogram to poll the mail server. If new mail is present, the email client “pulls” the mail to the client’s computer. The difference between this scheme and push email is that, with push email, the mail is pushed through to the client without waiting for polling.

Push email can be somewhat simulated using an email client set to frequently poll for new mail. However, this requires the email client to be open and running and is less efficient. Polling involves “handshaking” between the client software and the mail server. If the server is busy, the delay in completing the handshake can lengthen, causing the client to time out.

Therefore, polling should not be set so frequently as to cause premature time out errors. To prevent this, one must increase the delay between polling times. In many cases, a minute or two delay between “pull email” and push emailschemes may not matter, but in some cases, a minute can make all the difference. Push email can be especially crucial to field reporters, stock market businessmen and other professionals for whom time is of the essence. A one-minute delay can make all the difference in breaking a story, losing money, or making a crucial sale.

BlackBerry was the first personal digital assistant (PDA) to offer push email and gained near-instant success as a result. Today, many devices have incorporated push email, and its popularity continues to grow. Some of the products that have incorporated push email include Chatteremail for Treo, Nokia Intellisync Wireless Email, Roadsync, and Sony Ericsson phones.

Three things Nokia’s Ovi Store needs to fix

 

With a fanfare of crashing servers, Nokia has launched the Ovi app store. But now that it’s up and running, does it have what it takes to bring mobile phone apps to the masses? We took the Ovi Store through its paces and came up with three important ways it needs to pull up its shorts if it’s going to keep users coming back for more. 

 

1. Get good content

Before the Ovi Store was even a twinkle in Nokia’s eye, developers were coming up with heaps of great apps for the Symbian operating system. Sure, they’re a pain in the bum to install, and they’re tricky to find, but they’re out there. For example, every Londoner’s favourite navigation aid, the A to Z, has a mobile version with searchable maps that don’t need GPS and don’t rack up any data charges. Handy? You’d better believe it. Available on the Ovi Store? Nope. 

There could be many reasons why A to Z chose not to go with the Ovi Store, or Nokia didn’t want it–the A to Z company is notoriously sticky about how it distributes its treasure trove of London knowledge. But without good apps, the Ovi Store is just a proof of concept, not a useful tool, and Nokia should have moved heaven and Earth to get all the existing apps out there on board. 

Instead, we get a selection of Star Trek movie tat, and a £6 tarot card app. Meh. 

 

2. Get the Ovi Store’s own app up and running

We had to put down our sleek little E51 and bust out our clapped-out N95 to get a look at the specific application that’s supposed to make accessing the Ovi Store easier. To get the app, we went through the Download menu and refreshed the catalog until we could see an Ovi icon–a rigmarole that reminded us why we need the damn store so badly in the first place. 

The Ovi Store app is a vast improvement over the Web-based version (accessible at store.ovi.com), however, both in terms of looks and usability. The option to filter and sort apps is just a click of a button, for example, rather than scrolling down to the bottom of a Web page and manipulating drop-down menus. So why isn’t it available on all the Nokia smart phones, at a minimum? 

Nokia should have chained its teams of developers to their elegant Finnish desks to make sure it would be ready for most smartphone handsets at launch. Otherwise, it just goes to show how tough it is to develop for Nokia’s huge range of phones, when Nokia should be making it look easy–and showing off a slick, user-friendly version of its store. 

 

3. Make installing apps faster and easier

The Ovi Store should help us jump the two hefty hurdles to getting the many great Symbian apps on to our Nokia phones: They’re hard to find and they’re difficult to install. The store should help with the first one, by putting everything in one place and delivering only those apps that are compatible with your handset, rather than taking the brain-teasing “which version of Symbian?” quiz that was required with most apps. 

But making apps easy to install is just as important, and that means keeping clicks to a minimum and making messages easy to understand. But downloading some apps, even free ones, from the Web-based app store took us six clicks from the app’s page, not including typing in our username and password. The process of paying takes even longer. And once the installation has started, there are the same old cryptic messages that flash on screen that we’re using to seeing from installing Symbian apps before the Ovi Store. That means confusing error messages and seemingly random confirmation requests that seem to time-out in milliseconds. 

Finally, once the application has installed, it’s up to you to find it–and on a Nokia, this has always been a treasure hunt. Of the three we installed, one ended up in the Applications menu folder, one got its own folder in the main menu, and a ringtone opened up right away, to be saved into the phone memory or discarded. 

The Ovi Store should rule this behaviour with an iron fist to make sure users feel comfortable that once they pay for an app, they’ll be able to find it–and uninstall it–easily. Apple’s App Store made mobile phone apps the buzzword of 2009, not by having the greatest content–just ask a Windows Mobile user about all the cool stuff they can get–but by being so easy to use that anyone could find and install apps. 

Nokia, with its cornucopia of different phones, has a much greater challenge when it comes to building an app store that works for everyone. But if it doesn’t master it, it could go from mobile dominator to mobile dinosaur.
