I'm leaning towards the XPS 13 because of the price, newer processor, appearance (looks higher quality, though it may not be), and the better battery life.

However, I'm scared of the small storage. 128GB seems way too little, even considering that this won't be my main PC and that I have two 4TB external drives that I use for my data. I plan on using the laptop for work purposes 95% of the time, but between Windows 8.1 and all of my development tools (VS 2012, MS SQL Server) I'm afraid I'll be using half of it already, barely leaving space for anything else. Any .NET developers out there making it all work with 128GB?

Any opinions?
 
Solution
The 128 GB SSD on the Dell would be a deal breaker for me. The only advantage of the Dell is the longer battery life. The processor between the 2 machines is almost the same, as is the RAM.
