### **Conclusion**

This system uses a low-power SOC, and it’s not built for heavy-duty stuff like 3D modeling or video editing. The Snapdragon processor and GPU can handle lighter tasks like media consumption, data analysis, and basic content creation. The hardware is compelling; the Lattitude engineering comes through. And one day, the Dell Latitude 7455, or its successors, will be a good fit for those prioritizing efficiency and collaboration or anyone juggling a busy workload — once the Windows ARM experience matures.

[](https://www.storagereview.com/storagereview-dell-latitude-7455-1) 

Over the last few weeks of testing, we have noticed improvements in the Windows ARM OS and firmware and driver refinements, so we’re optimistic about improvements. If the user workload is browser and Microsoft Office-based, with only occasional dips into the non-ARM Native ecosystem, this system will deliver well. But even in that base-case scenario, it’s hard to justify this hardware expense for users who stick exclusively to the ARM-friendly realm. Dell has many other better choices for those wanting a thin and light portable experience that costs much less.

It’s hard to fault Dell here. Specifically, they wanted to get on the Snapdragon train, and for a good reason: the integrated AI potential is impactful. But Microsoft needs to rapidly resolve what’s essentially a Beta OS at this point. We have faith, but this modern Windows/Snapdragon journey is going to require a lot of patience.
