Ahh, I see. The words "gaming laptop" typically implies that you would like your laptop to be able to run modern games to some degree, hence my confusion. As for travelling, I find that my 15.6'' laptop is just a tad too bulky to lug around everywhere comfortably, but iit's not a huge pain in the ass. I certainly wouldn't recommend carrying around a 17'' one or even something larger, though. RuneScape's performance is mostly processor-bound, and just about every graphics card should be able to handle the graphics side of things. Personally, I'd look for something that has an Intel i3 processor or better, and some form of dedicated graphics card that isn't at the complete lower end of the spectrum, and that's it. That should easily fit within your 700 pound budget. The laptops Kim and Z_Berenice suggested both qualify just fine, and quite frankly, every electronics store in your area should have something that suits your needs. Why not visit a store and try out a few laptops? See if you like the touchpad, the feel of the keyboard, the quality of the monitor, the feel of the laptop's casing, etcetera. Such things can be hard to figure out online, without doing lots of reading. Just don't listen if the salesperson tries to trick you into buying some super-powerful model :P To add in something myself, I'd suggest this one, mostly because I have good experience with Lenovo myself (my old Thinkpad is Nokia 3310 kind of sturdy), and because it includes a solid graphics card and a modest SSD which is quite rare at this price point. That said, you can get by with a laptop that's quite a bit cheaper than this one.
