I'm currently using a 2014 Macbook Air, and it's extremely sluggish, even just browsing (using Chrome and having 10+ tabs open). This is despite me having wiped it and reinstalled the OS (and upgraded).
Thinking about getting this - https://www.officeworks.com.au/shop/officeworks/p/lenovo-15-…
Thoughts? Will it be a noticeable upgrade?
A 2014 Macbook Air shouldn't be sluggish at all especially for just browsing, spend a bit more time trying to diagnose the issue. Swap Chrome for Firefox or Safari.
The Lenovo runs Windows, are you prepared for OS change? You're going from a premium metal (albeit older) to a basic plastic cheap laptop (albeit higher spec), are you happy with that trade-off?
