Your wifi could easily be upgraded with the money you saved from the lap top. All you need is a good 5g router. Honestly I would listen to them. he best laptop you can find is probably not going to give you the experience you would hope for, especially with link.
I wouldn't choose a lappy for that until you've read several reports of folks having no issues with link on it.
