Toshiba to land the ultrabooks market with its first ultrabook, Portege Z835 with a Best Buy exclusive at a price about $900 which happens to be $200 less than the price at which the ultrabook of Asus is available and $400 less than the price at which Apple is offering its baseline 13.3 inch MacBook Air.

And it is equally interesting to note that even when priced at such affordable rate, it has a great deal of things to offer. In fact, some reviewers have found it to be offering more features than Asus and Acer.

You get a display of 1366X768, Intel Core i3-2367M processor of 1.4GHz, RAM of 4GB and a SSD of 128GB under the brand name of Toshiba. But there are a few things which will disappoint you a bit like the color and presentation of the notebook is not elegant enough to be called splendid, again its flash drive isn’t that smart as one will expect as it offers a sequential read & writer speed of 185MB/s and 49MB/s that aren’t above the standard 7200RPM hard drive. Coming to Its SSD, it doesn’t do anything beyond imagination.

But then, you have good things that will make you happy. It weighs light with about 2.4lbs lesser weight than the ultrabooks competing it. Its battery life performs much better than those of Zenbook and MacBook Air, so you get a battery life of about 7 long hours when you use Wi-Fi for browsing the internet. Its connectivity offers you USB 2.0 and 3.0 ports, VGA and HDMI out, Ethernet and a card reader.

But what sounds a bit disappointing for Intel and its partners is that ultrabooks didn’t start off that well.  Just in the earlier part of this month, companies like Asus and Acer were expecting to sale out about 100,000 units of their ultrabooks by the end of 2011, which was third of what they had originally targeted. According to the media, Asus and Acer have brought out much lesser than they were expected to do as they have reduced the orders for the ultrabooks by flat 40%.

It is notable that both the companies are pretty certain about the platform for longer time.

Acer is finally entering the “ultrabook” market with its Aspire S3, its first ever ultrabook which claims to be a good featured set at a price below $1000.This 13.3 inch tall, 0.51 inches thin device, weighing 2.98 pounds will be available by this week itself. The body of Aspire S3 is made up of magnesium alloy and you get an Intel Core i5 processor, a solid state drive operating system of 20GB, and the current state of the machine under its hood along with a storage hard drive of 320GB.

A resolution of 1,366 X 768 pixels is offered by the LED-backlit display of the system and it is the integrated Intel HD graphics 3000 graphics processor of its CPU that drives it. Its major specifications include – connectivity options like 802.11 b/g/n Wi-Fi, USB, HDMI ports, 4.0+ HSR, also offers a head phone port and memory card reader. It comes along with a standard RAM of 4GB.

It claims a battery life of 6 hours when used continuously and an extra-ordinary 50 days when left at a standby. There is a special Green Instant On feature that brings the system out of the Sleep mode in mere 2 seconds and out of the Deep Sleep mode (i.e. when it isn’t used for 8 hours) in just 6 seconds. The bottom vents have also been removed and instead the machine has been tweaked for the efficient dissipation of the heat.

The Aspire SE 951 will be available by this week in U.S. and Canada at a suggested price of about $900. Acer also has plans of launching other Ultrabook models which will be offering Core i3 and Core i7 processor options along with larger SSDs; however no release date or pricing related details have yet been announced. If we compare Acer’s Ultrabook with the 13 inch MacBook Air from Apple, it starts at $1,299 and offers a dual-core Intel Core i5 processor of 1.7GHz, flash storage of 128GB, and a standard 4GB RAM.

Walking the same aisle on which Toshiba and Lenovo are making a move, Acer has finally decided to be a part of the Ultrabook battle at the IFA trade show to be taking place in Berlin. Acer will be officially joining it with its Aspire S3. The chic device offers a display of 13.3 inch or 1366 X768 pixels, thickness of 0.51 inches, uses low voltage Core i3, i5 or i7 Intel processor, on-board flash memory usage for quicker starting up time and caching for performing faster.

It has a neat frame made out of aluminum-magnesium alloy, and a form factor that reminds of MacBook Air line form Apple. Though the specifications aren’t very clear at the moment, it seems apparent that Acer will be offering storage of 240 GB SSD or 500 GB HDD.

The other features of the notebook will be including HDMI port, a pair of 2.0 ports, webcam of 1.3 MP, 2-in-1 SD card reader, a single headset jack, Wi-Fi of 802.11 b/g/n and a Bluetooth of 4.0+HSR.

A full size chiclet keyboard as well as a multi-touch trackpad of slightly large size coming along with mouse buttons will also be offered by the device. Acer even promises 7 hours of battery life for its SSD equipped model making it apparent that the models with hard drive are going to offer lesser battery life.

Acer is looking forward to sell its Aspire S3 in some select regions from a later part of this month at a price of 799 Euros or $1, 138 and moving up to 1, 199 Euros or $1, 707 that will depend on the specifications the buyer will be choosing.
