++ Good looks, also allows you to uninstall software quick
++ not intuitive, overly complicated, doesn't recognise most of my software and relying on software partnerships as explained on their website.
A lot of these tools actually add in unnessecary information. Why make a program that is meant to make things simple so complex? all the different options of showing or not showing certain kinds of software, vague labels such as "more information" and a badly layed out results screen (after a scan) don't help anyone.
It's not intuitive, for example some software have multiple download links, only when they're downloading you notice they're different versions -- but both the buttons are called download.
I like the piechart as it gives a visual overview of how much software is out of date. Also the purchase option could be something to look into for DcUpdater as they could perhaps link to the DC discounts (try and buy the software on discount this month directly via DcUpdater)
I like how DcUpdater focuses on the new instead of the old. It's not just about what software is out of date, also what addons are out there or what's new in softwareland.
And Updatestar sits in your systemtray 24 hours a day even if you choose only to update once a month (this can be disabled but is a bad default). We've got a capable Task Scheduler in modern OSes that hardly gets used. Come'on.
And yes I really need to sit down soon to do the reviews of all these similar software for Mouser (sorry man).
