Second Chance: Desktop Processors In A Mobile Form Factor
Краткое содержание статьи: Recently, we reviewed the Dell SmartStep 250N. Things did not exactly proceed as planned in our review of this product. Now, we look at the WinBook J4 that uses a totally different strategy for throttling the Pentium 4 Northwood desktop CPU in a mobile form factor. The J4 has some very unique features that allow it to rival some desktop systems. When coupled with a 3.06GHz non-HyperThreaded CPU, what will the result be?

The WinBook J4 - Specifications and Background

The Winbook J4.

The WinBook J4 appears, at first glance, to be a notebook that nearly anyone can afford. With configurations priced as low as $999 US, it is clear that, like the Dell SmartStep 250N, WinBook's goal with the J4 is affordability along with features that most users would like to have in a power notebook. Let's take a look at the specifications of the J4.

The J4 offers a 1x" SVGA+ display with a max resolution of 1400x1050. The ATI Mobility Radeon 9000 (M9) with 64MB of video RAM feeds the display. We would rate the display quality as excellent. The Mobility Radeon in the J4 unit was clocked at 260MHz core and 200MHz RAM.

The J4's case is made of plastic and metal which is finished in black. This color scheme is a return by WinBook to its all-black color scheme, which had changed to silver and grey finishes only in recent years. The J4 is neither light nor slim, checking in at the following dimensions: 13.07" (332mm) x 10.8" (275mm) x 1.64/1.81" (41.8/46.2mm) overall; back to front height of 1.64"/ 1.81" (41.8/ 46.2mm) (front/ back); typical weight is 9.5 pounds (4.3kg), which puts the J4 in the "heavy" category. Most of its weight is due to its 12 cell LiIon, 87.02 W/hr battery, which has a recharge time of 3.5 hours with the system off.

When it comes to connections, however, the J4 is loaded with everything that you could ask for. The back of the unit includes a headphone jack, mic jack, printer port, VGA port, S-Video out, modem jack, and AC in. As you can see in the picture below, the J4 unit includes two vents on the back of the unit to help with heat dissipation.
