I am wondering the same thing! I have girls 9 and 11 who love Minecraft and Roblox. That's all they really want them for, and YouTube and maybe to watch movies. I was at Best Buy yesterday and a guy kept showing me the ones with the graphics card in the $800-$1300 range. I said under $300? He said with games like Minecraft it will work fine for a while but once they start building larger worlds it will get slower and slower and may eventually stop working. I told him I didn't want to spend $800 for a 9 year old who may drop the thing! He recommended a desktop as you get more for the money. But of course the kids want to be able to take them everywhere. So I'm feeling stuck:(
My child has been playing both Minecraft and Roblox on my laptop for over 2 yrs. The laptop is 4 yrs old. It was a nothing fancy blackfriday special and they both work fine on it. He some days will play 6-8 hrs at it with no problems as well as watching You tube on it. I still do all my other stuff on it.
