I used one last week it was fine. If you don't insist on having 15 apps open and 30 tabs in safari, as it seems people are completely incapable of closing anything these days and you keep one or 2 things open at a time (which will be fine for the OP's stated use case) then 2GB runs great. It's not the apps or OSX that is requiring masses of ram these days it is peoples lazy computing habits and unrealistic expectations.
So you're saying use computers like they were used 10 or so years ago to justify having to little ram. Sure if you use a mac with very little open (similar to usage in times past) you'll probably be fine, but in reality a lot of people don't do that, as computer usage has changed. People use a lot of applications and tabs at once.
