Time to spend them 
Let's say up to a grand to spend upgrading your second laptop. Less is good but decent is also good!
Intro:
So what I want is a replacement portable laptop. Priorities are a decent CPU (i5 or better would be nice), around a 13" screen with a decent res (ideally 1680x1050) and a decent battery life of 8+hrs, please! RAM and storage are not concerns as they're both easily upgraded, though ultimately I'll be putting in a 512GB SSD and 8GB RAM.
Any suggestions?
Cheers.

Let's say up to a grand to spend upgrading your second laptop. Less is good but decent is also good!
Intro:
Currently have an XPS 15 with bells and whistles (i7-2820QM, 16GB RAM, 256GB SSD + 2nd HDD, 1080p screen etc) for my main one. This sits where it is and doesn't get moved.
Then we have my portable laptop for taking places around the house or elsewhere. I'm currently rocking an oldish Asus UL30A with a ULV 1.2GHz dual core, 13" 1366x768 screen and 7+hrs battery life that I've tried to beef out with 8GB RAM and 160GB SSD.. but it's unfortunately still slow as a dog due to the CPU, doesn't have enough storage and the screen's too low res.
