No brand listed, but leaving that aside I'd recommend a business class laptop, that should easily last you 2-3+ years in terms of build quality. That said, I'd find out which one supports the highest capacity SODIMM modules. Some only support 4GB per module, the newest ones may support 8GB modules. If you only have 2 DIMM slots, I'd recommend finding one that can support 8GB modules, which will let you cram 16GB into your machine in the future. I'd also only purchase 1 DIMM from the manufacturer, unless you can get the 2nd one at dirt cheap prices because they usually way overcharge to add higher capacity or a 2nd memory module. Generally it's easy enough (except MacBooks) to add in a 2nd, or replace both modules and buy them from a 3rd party like NewEgg. Plus you'll save a bunch of money. That's what I did with my Lenovo, bought it with 1 4GB module, bought another 2 4GB modules (I have 4 DIMM slots), and so now I have 12GB of memory running in my laptop which is plenty for Lightroom/Photoshop.
The other thing to consider is if you are going to be doing any gaming, or anything that can take serious advantage of the GPU I'd look into getting a somewhat beefier one. I'm not really up to date on them GPU scene these days, so I'd read around to see which ones are better.
