Watch out on the intel side of things, laptop CPU's differ from their desktop counterparts. For example on the desktop side an i3 is dual core with hyperthreading (2 core 4 threads), an i5 is 4 cores, an i7 is 4 cores (usually but more on there more expensive i7's) with hyperthreading (4 core 8 thread). On the other hand on the laptop side there are i5's that are 2 core 4 thread. So be careful, however I do suggest a intel CPU and I suggest it be either Broadwell or Skylake. Something like this http://www.newegg.com/Product/Product.aspx?Item=N82E16834315167 maybe. Also 8gig minimum, and if you plan on developing and multitasking at the same time 16gigs will serve you well. If you up your budget to approx 650 you can get a small discrete gpu.
watch out for the OPs requirements.
any mobile intel chip, starting with core i series, will be enough. Even the ULV ones (they are weedy compared to desktop chips but more than enough for 2D development).
16 Gigs are clear overkill... doesn't hurt, but usually bumps up the price of a laptop which comes in fixed configurations way higher than 500$. I would even say 4 Gigs might be enough, given the modest requirements of the OP.
Is buying a 4 Gig machine in 2015 future proof? Most probably not. On the other hand, if I had to choose between a bad screen and only 4 Gigs of RAM, I would know where to cut corners
A discrete GPU is clear overkill for the OP, and in fact under a GTX 960M equivalent (laptops with this card start at 1000$, double the OPs budget) a discrete GPU does not make much sense... a modest bump over the iGPU you pay for anyway, additional draw on the battery, all that for money that would be better invested into a better screen or a better CPU.
I think the most important thing to not cheap out on is to get a newest generation CPU and graphics chip, because you will curse yourself in a year or two if you can not test properly as your computer does not support a newer version of graphics API or instruction set you want to use.
An extra graphics chip is nice cause Intel is the fastest to stop supporting older chips with the drivers, AMD and NVidia often support a higher OpenGL or DirectX version than Intel and its nice if you can test 2 of the 3 vendors implementations on a single machine.
Good point actually... Intel IS the unloved stepchild among the three GPU producers... given they are stepping up their game though in the last few years when it came to their iGPUs power and that the iGPU is the main selling point for new CPUs nowadays, is this still true?
And might that point be a good reason to try and hunt down a Laptop with a current gen AMD APU (if there even is such a thing), as their iGPUs seem to be based on their current gen GPU architecture... which might be supported for longer?
Atom, on the other hand, is just abysmal. My Odroid XU4 (not so much a laptop, but a credit-card sized mini computer) which is about 1/10 the price of my Atom netbook (and 1/10 the size and 1/2 the power consumption, too), performs approximately equivalently to a 3-4 year old desktop computer (you can tell the difference from whether a full rebuild takes 5 minutes or 50 minutes!). The Atom performs about the same as a 15 year old computer. I so totally regret ever buying one. May the guys who designed Atom rot in hell forever.
Not wanting to really put the Atom chips on the same level as any REAL PC CPU, but they have come a long way since the day of the netbook. Check the tests for the Surface 3 or the newest generation Atom x7.
Quadcore and JUST about fast enough for everyday work (provided you don't do hardcore photoshopping or anything else demanding)... while still being quite frugal when it comes to powerdraw.
Seems like after all these years, "netbooks" finally start to make sense as the "netbooks" of 2015 no longer choke on a simple website
Still, the ONLY real use case I see for such a CPU is for a lightweight MS Office/Mail/Surfing device to lug around all day. That is why the Surface 3 LTE sounds great... before you look at the price.
But I wouldn't try to do anything more than write a GDD on this thing... or maybe some quick doodles (yay for stylus support!)

Under 500.
Intel chips.
Are you guys on Intel Payroll? Or just talking shit?
i3 are absolutely far beyond what a starter needs.
I strongly suggest to take a look at AMD Carrizo laptops.
If one can find a Laptop with AMD Inside, go for it... but there aren't that many around.
On the other hand I regularly see laptops with i3 and i5 chips popping up even around here in switzerland where we pay at least 25-50% more than in the US for the equivalent of 400-500$ during store sales.
They might not be the most attractive machines in the world, not ultraportable (most are 15"-ers and as non-ultrabook as they can be), but they got acceptable core i mobile chips and a decent amount of RAM.
Never was interested enough to check the other specs, I fear most of them had crap screens, that is definitely what I would check first.
But they do seem to exist, even if you have to wait for a sale (which seems to happen often lately... I guess with the PC Market shrinking, sellers are desperate to move their ware)
About i3s being beyond what a starter needs... well, as soon as you start up Gimp or any other tool needed for 2D development and use some of the heavier options or a bigger resolution file, you will be thankful not having to put up with the slowest chip out there.
Having said that, I like the idea of getting an old, used machine. As long as it is cheap as hell (used PC Parts could fail any minute... or last a lifetime, you don't know... and nobody will give you any warranty for it), why not see what you can get on E-Bay or Craigslist?
If you want less hardware russian roulette, go to a used hardware store... we have several here in switzerland that sell used Business laptops. these things might only have served for 2-3 years in some companies (though given the recessions of the last few years, most companies will exchange hardware less often), will have been good midrange machines when they were rented/leased/bought by the company, and most probably come from big well known brands like Dell, HP, IBM...
You might get a good deal with such a used laptop.
