Pros

  • Early beta tests suggest that the OS will be quicker than Vista

Cons

  • Too soon to make a proper assessment of the operating system

Bottom Line

It's way too early to make a proper assessment of Windows 7, but Microsoft has made its intentions clear: Windows 7 is intended to right the wrongs Vista wrought, but retain that operating system's good points. And at this point, we can't argue with that. Our early beta tests suggest that the OS will be quicker than Vista, which can only be a good thing. We'll be updating this review as we get more information on and time with Windows 7, so be sure to bookmark this page.

Windows 7: performance enhancements

Some of the biggest criticisms of Vista relate to performance, and Microsoft appears to have made addressing these a priority. In our brief experience with the early-beta code, boot time seemed fast. Of course, we won't be able to make a fair comparison until we can test identical machines with the same bare-bones installations in Vista and Windows 7, but Microsoft did identify a couple of steps it has taken to speed things up. First, Windows 7 initialises many services in parallel; and second, it has fewer services to initialise.

Microsoft engineers are working on several areas to improve general PC performance. One focus is to change the way the OS allocates memory to new windows. In Vista, the amount of memory allocated per window goes up as you add windows, to the point where the system often shuts down Aero because application windows are soaking up too much system memory.

In Windows 7, each new window will be allocated the same amount of memory, and as a result adding new windows won't impose a prohibitive burden on system resources.

Other changes are designed to make the OS less crash-prone. Fault-tolerant heaps, for example, are designed to address memory management problems without crashing the problem application; at the same time, process reflection reduces crashes by allowing Windows to diagnose and (maybe) repair process problems without crashing the application involved.

Microsoft says that its new OS "sandboxes" printer drivers so that problems stemming from poorly written drivers won't create problems for other drivers or for the system as a whole.

Microsoft is also working on ways to prolong notebook battery life by reducing power consumption. Examples of this endeavour include enabling notebooks to cut back on background activities, to perform intelligent display dimming (similar to technologies used with cell phone displays), and to play back DVDs more efficiently.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
