Nokia introduced its premium enterprise mobile phone, Nokia E90 Mobile Phone to the world market along with a promise that, this model, with its exceptional lightweight and added 3G connectivity, would provide the user with a great and light travel. This is even evident in their punchline, describing this gadget as nothing less than an office taken for a trip by the executive. From these, it is also evident that Nokia had launched this mobile phone with a view to exploit the business sector. They gave immense stress to the lightweight of 210 grams here along with the 3G (UMTS) connectivity feature. This is fairly for the fact that Nokia E90 comes in the lineage of the Nokia 9500, 9300 and 9300i business class PDA like mobile phones, all of which collectively lacked the 3G connectivity aspect that in its turn very much explained the sluggishness of these models in data transfer sphere. Moreover, even at a leaden 210 grams, the E90 mobile phone is 20 grams on the lighter side of the 9500 mobile phone. This large and wide clamshell model explains its dimensions with 132 x 57 x 20 mm.

Meanwhile, Asus M930 Smartphone Mobile Phone is considerably lighter than its rival at about 158 grams of weight. The dimensions of this business class mobile phone (113 x 54 x 18.7 mm) also prove it a better device than Nokia E90 at least in terms of portability. This mobile phone too has a clamshell like form factor, where the keyboard and the display screen is separated very much like a conventional laptop PC tends to do it. This mobile phone from the Asus bckyard definitely comes tagged as an E90 killer as if the myriad features in it do not talk for themselves. Asus has choosed the mighty Windows Mobile 6.0 operating system for its flagship as against the Symbian Version 9.2 operating system driven Nokia E90 mobile phone. However, Asus M930 mobile phone that engages a TI OMAP 2431 processor of 450MHz clock speed has obviously stepped a foot backwards by employing a triband GSM aspect against the Nokia E90's quad band GSM network support. Otherwise both the models possess almost identical connectivity features like HSDPA 3.6, UMTS (3G), GPRS, EDGE, Wi-Fi and Bluetooth. Although not of considerable significance, the fact that Nokia E90 offers an infrared feature for short distance, device to device wireless data transfer is worth mentioning here.

The sector, where Asus M930 mobile phone excels despite its compact design is the storage capacity sphere. The internal memory of this device refers to a satisfactory 256MB as Nokia E90 mobile phone has only a 128MB on-board memory. Consequently, both the models offer expansion slots suiting microSD cards. Asus M930 also trails in the display screen part with only a 2.6 inches diagonal sized TFT of 400 x 240 pixels resolution to boast as the N90 Communicator proudly presents a magnificent active matrix TFT of 800 x 352 pixels resolution and 16 million colours. The external display screen of the E90 mobile phone is also studded with as much colours and 240 x 320 pixels. Messaging features in both these models too are almost indistinguishable with both the gladiators having stacked their quivers with the best lot one can get anywhere in the market such as Push E-mail, Instant Messaging, various Email protocols like IMAP 4, SMTP and POP3, MMS and SMS.

Nokia E90 Communicator mobile phone, outclasses its opponent in one segment comprehensively, and that is the GPS segment. While the E90 smartphone has an integrated GPS receiver and pre-loaded Nokia Maps to help one in positioning as well satisfactory navigation, its opponent falls flat here, without much to offer in this field. The E90 Communicator mobile phone also excels in the imaging sector with an integrated primary camera that in its turn flaunts a 3.2megapixel sensor, built-in flash, autofocus, camera settings and scene modes. Meanwhile, Asus M930 mobile phone has only a 2MP camera to tout and this camera lets night shots and desired subjects in darker conditions go begging with the absence of a built-in flash. The music player of the Nokia E90 is also shade better than the one sported by the challenger, Asus M930. Nokia E90 not only offer support for MP3 and AAC formats but also features an FM radio for enhanced musical bliss. Here too, Asus M930 takes a step backwards for it has only a Windows Media Player to offer.

Finally, the power management and battery life in both the models are equally excellent, though as anyone who knows something about mobile phones or like gadgets can presume wisely, the larger model can offer better battery life more often than not, simply due to its size. This norm can be applied here too, as expectedly Nokia E90 Communicator offers 5 hours of talktime and 14 days standby against 4 hours talktime and 200 hours of standby extended by Asus M930 mobile phone. A look through these facts, obviously points to advantage Nokia E90, though the challenger definitely cannot be wrote off, for the user-friendliness, ergonomic compliance and above all, convenience of portability that shrouds Asus M930 PDA Mobile Phone.
