First time mac user!

Dear applecore folks,

I recently purchased macbook air mid 2012 13'' basic model. Just to tell you guys, its my first ever OSX device and before that i have been using windows for years(still using it). Right now, i use three different OS, windows osx and linux mint .

So my issue is, i find macbook air to be slow. i think the animations are choppy and scrolling is terrible. Scrolling is real terrible on chrome, a bit better on safari. Theres also input lag sometimes, so my question to all macbook air users, is it normal ? i have 20 days more to return it and get money back.
