Unlike Vista, 7 seems to be generally regarded as better than XP. If it's already installed, you might as well 'give it a go'.
However you need to be aware that there are 6 different editions of Windows 7. See the comparison table here for the details:

New laptops often only have the Starter Edition, which can lead to some frustration when, for example, you find that you can't change the Desktop (unless you install a third party program which actually leaves the Desktop unchanged but then puts another picture on top of it).
Similarly, 7 was designed with 'XP Mode' built into it, specifically so that people like you could use your old software and techniques but (annoyingly) Microsoft have only enabled that feature in the most expensive editions of 7.
