Don't know if specs matter but here's mine: - 13" MacBook Air (mid 2013) - 1.3GHz i5 - 8GB RAM - 256GB storage - OS X 10.11.11 - Windows 10 Bootcamp El Capitan is really good because it reversed much of the problems Yosemite had. - Battery is somewhat better now - Speed seems to be slightly better - Air Drop works - Split View is actually pretty good - Wi-Fi issues were fixed Now there's still a ton of stuff I'm not a fan about like iTunes/Apple Music, Photos app and iCloud but I'm willing to settle with El Capitan as my last OS X upgrade. It works good enough now that I really don't want to regret upgrading it again and have it run like Yosemite again. Here's the shocker though. Some may know that Blizzard's new game, Overwatch won't be coming out on OS X. So I bootcamped Windows 10 really not expecting much. I've heard some great reviews but I've been used to Windows 7 and am not a fan of Windows 8's design. Couldn't believe how fast Windows 10 is in everything. It just feels faster and looks smoother, its so noticeable in opening any apps. I mostly use Chrome and Spotify. Even the built-in apps. Really I'm just shocked at how fast Windows 10 is. Maybe its some app that slowing down my Mac? I basically only use Apple stock apps and well known apps like Chrome, Spotify, Microsoft Word. Is it Dropbox? I've rectory reset my Mac a few times usually when new OS X comes out. I'm trying to find some sort of excuse besides maybe the fact that OS X is just not as fast anymore? Is it my MBA? I mean its not the best spec'd Mac but it should be fine, its like 2 years old. Windows 10 makes El Capitan feel slow.
