I think it depends on the software and the audience you are going after. Something like Windows 7, there are casual PC users and hard-core PC users. You can design a review around which audience you are going for. Something like Dreamweaver...chances are they are more technical and the review should probably cover more technical points of the software. Screen Shots are always helpful too.
Writing a review of computer software you are using or have tried can be a good way to earn money on Associated Content, as well as computer magazines and other websites which pay for software reviews, or to add content to your own website. It can also be considered a good way to decrease the cost of buying software, if you know that some or all of the price will be earned back by writing a review. Before writing your review, try using nichebot.com or nichebotclassic.com to determine if many people are searching for information on the piece of software in question, and conduct a search to make sure too many people haven't already reviewed it. Here are some tips on what to include when writing a software review... CAPABILITIES: After describing what type of software/program you are reviewing, provide a detailed summary of its features and capabilities. If it is an application, mention if there are multiple purposes it can be used for. Look through any drop-down menus the program has, to see if there are features you have overlooked. QUALITY, SPEED: If applicable, describe the quality of the graphics and/or sound featured in the software. Be sure to indicate if the program runs too slowly (or too quickly, as can occur with some older software) on your computer, and mention your computer's processor speed (if you don't know this, you can check it in Windows XP by clicking "System Information" under "System Tools", in the "Accessories" Start menu, and then looking for ___MHz on the "Processor" row). To be fair, don't run any other programs at the same time, and make sure no virus scans are running in the background. Try the software on more than one computer (with a different processor and/or operating system), if possible, and describe the difference in performance. Mention any errors or other problems you encounter in the software, but remember that your computer's particular configuration may be partially to blame.
