In just only five months, Palm managed to sell one million Centros, the company announced in a press statement. Palm is selling Centro in ten countries worldwide. The smartphone was launched in the US in September last year as a Sprint exclusive and in February this year it was introduced on the AT&T network.

Palm Centro is powered by an XScale processor and it comes equipped with 128MB of ROM and 64MB of user-accessible RAM. Of course the storage capacity can be expanded through its SD card slot, which can handle cards up to 4 GB. Centro has a touch screen capable to display 64K colors at 320 X 320 pixels and it integrates also a 1.3 Megapixel camera with 2X digital zoom that can handle video. According to Palm, Centro’s battery offers 3.5 hours of talk time.

Centro is ideal for those who like to have a full QWERTY keyboard to type their messages. Plus, Centro keeps all your conversations in a chat-style view, just like IM, so you can see the entire conversation unfold. The Palm Centro offers direct access direct access to Yahoo, Windows Live Messenger or AOL's AIM service.

Centro comes with the Palm OS, it offers all of the great organizer functionality that Palm is renowned for, such as a detailed and integrated Contacts list. Also, the simple and handy calendar makes it easier to manage increasingly busy lives, whether it’s juggling business meetings or keeping track of school activities.

Centro is recommended also for those who want a easy mobile email solution as the phone uses Microsoft Direct Push Technology for delivery of Outlook email as well as personal email, such as Gmail, AOL and Yahoo.

"The Palm Centro is flying off the shelves because users who want to step up to a smartphone see it as the perfect first choice," said Brodie Keast, senior vice president of marketing for Palm, Inc.
