ony Ericsson Xperia X1

The X1 is an arc-slider phone with the Windows Mobile 6.1 Operating System. It is Sony Ericsson's first mobile phone to feature Windows Mobile.[1] . The device also has a Java virtual machine (JBed) and supports JavaME [5] that is claimed to have a richer set of features than typically available.

The phone features a three-inch resistive touchscreen overlaying a keypad which emerges when the user slides the touchscreen face upward, much as in the HTC TyTN II, although the X1's touchscreen slides out in an arc. Its touchscreen is a 65,536-color TFT WVGA display. It has a 3.2 megapixel digital camera which records video at thirty frames per second in VGA (640x480) quality. There is also a secondary front facing camera for videoconferencing that is of QCIF format. Connectivity options for the phone include: mini-USB; wireless LAN 802.11b/g; Bluetooth 2.0 with A2DP, FTP, and HID; EDGE; and quad-band GSM, UMTS, HSDPA, HSUPA, and HSCSD. The X1 has 512MB of internal memory (400MB free), which is expandable to 16 gigabytes using High Capacity microSD cards, currently cards up to 32 gigabytes have been released by SanDisk.

Nokia N800

The Nokia N800 Internet Tablet is a wireless Internet appliance from Nokia, originally announced at the Las Vegas CES 2007 Summit in January 2007. N800 allows the user to browse the Internet and communicate using Wi-Fi networks or with mobile phone via Bluetooth. The N800 was developed as the successor to the Nokia 770. It includes FM and Internet radio, an RSS news reader, image viewer and a media player for audio and video files.

Nokia N73

The Nokia N73 is a smartphone by Nokia officially described as a "multimedia computer". In common with other Nokia 'Nseries' and 'Eseries' phones of its time (late 2006), the N73 comes loaded with many software applications, including contacts, messaging, picture and video galleries, a music player, a Visual FM Radio, RealPlayer, an IM client, a WAP browser, a full web browser based on KHTML/WebKit, a Microsoft Office document viewer, a PDF viewer, an Adobe Flash Lite viewer and some games. The majority of these applications support background execution; for example, one may listen to music while browsing the Internet, and then may switch to write a text message or e-mail, without having to close any applications. With the exception of newer Sony Ericsson phones like K550 and W610, non 'smartphones' typically cannot do this or can do it in only a very limited way; for example, only the music player can run in the background. The feature which most distinguishes the N73 from other 'N'- or 'E'-series Nokia mobile phones is the 3.2 megapixel autofocus camera. The N73 does not support Wi-Fi.
