CNET reviews the SonyEricsson P1 and writes, “Sony Ericsson did not include a full QWERTY keyboard on the P1i, but instead put all the letters and numbers in 20 keys. Most of these keys rock left or right to serve as different letters. For example, the top left key is used for both the Q and W letters. Rocking it left will get you the former, while rocking right will type the latter. The center portion of the keypad has numbers in red laid out just like a regular numeric keypad for use in the phone application and when filling out fields where numbers should be entered. While such a keyboard layout saves space, it takes some getting used to. Essentially, typing a letter becomes a two-step decision. First, you decide which button to land your finger on, then which direction to rock the thumb toward. You could just land your thumb on the side you want and press it immediately, but that means there is very little room for error when it comes to the position of the thumb tip, a real challenge for those with large fingers.”

Building on the feature set of earlier models, the Sony Ericsson P1 supports a wide range of push email solutions and Web browsing applications, plus connectivity via hi-speed UMTS and Wireless LAN (WiFi™). Add to this its compact size and multimedia capabilities and the P1 is the complete mobile office. It is based on the Symbian™ operating system (v9.1) and UIQ 3.0, an open platform that offers broad potential for multimedia applications from operators/carriers, content owners and third party developers.

MobileBurn reviews the SonyEricsson P1 and writes about keyboard “The QWERTY keyboard on the P1 is unusual in that the right and left edge of each convex shaped key serves a different purpose. As such, the ‘A’ and ‘S’ letters are on the same key instead of on neighboring keys. The shift key located in the bottom left corner of the keypad works as one would expect, and the ALT key, in the lower right hand corner of the keypad, is used for accessing the numeric keypad digits and symbols. A pair of arrow keys straddle the space bar, and they offer a bit of help when navigating the P1 without using the stylus. The number keys, when used with the ALT key (which can be locked on), work like they do on regular phones in that you don’t have to worry about the edges, you just press the key. The design is compact, but far from ideal. A year ago when I reviewed the M600, I adapted to its keyboard and learned to live with it. But now, after having been spoiled by many devices with fine QWERTY keyboards, I am less inclined to embrace it. Those extra few millimeters of width offered by the keyboards on devices like the Motorola Q or Palm Treos make a big difference. The P1’s keyboard is certainly passable for those that value a compact form factor over ease, and speed, of use - but it is not one that I am in love with. In any event, the keyboard is faster and easier to use than the touchscreen based virtual keyboard or handwriting recognition system.”

GSMArena reviews the SonyEricsson P1 and writes about camera, “The camera interface reminds a lot the interface of the latest Sony Ericsson phones and has a rather similar graphics and functions, but unfortunately is not as snappy as the one used in their feature phones. The highest resolution available is 2048 x 1536 pixels, which practically shows that the 3.2 megapixel sign on the camera is a marketing gimmick as the real resolution of the photos is 3 megapixel. There are three quality levels and the camera has a full automatic exposure control but offers nice manual overexposure control accessible from the main viewfinder interface.”
