This is the first Chromebook I had, I used window desktop and laptop for 15 years. I don't know how the performance compare to others Chromebook, for me is just enough to open about 7 tabs with 1 youtube video playing, in this situation it is slow to move cursor and click the items on page. If you try to playback the 720p60fps or 1080p YouTube, I don't think the processor is good enough to play it as it is lag it you try to do other command, if you try to adjust the video playback speed, it will lag after a few seconds and the video and audio is not synchronized.If you want to keep the performance just below the limit of this laptop, you can only open 5 tabs on the same time with 1 youtube video 720p or lower quality.The startup time is 2-3 second, but there will be 2 seconds wait for the chrome load up a page. There will be 5-10second of opening a Google sheet. The Google map is not smooth to use on this laptop, lag to zoom in/out.For hardware, it is a 1080p mon, 2x usb-c(only 1 can charging), 2x usb-A, 3.5mm mic/headphone, a micro-sd slot. 32GB storage, 11GB for android, 2.5 for chromeOS, 18.5GB rom only.For me is good enough for light use such as web surface, using Google doc, sheet to do some travel research, the shortcut is also very good, fast to open/close/switch page. But I cannot use it for daily, I only use when I am lazy to turn on the desktop/ not using for a long time/ take it out for discussion.If you are using a middle range hardware(say i5-4430) computer for a long time, I don't think Lenovo 14e Chromebook can reach your standard of a computer, maybe you can try m3 core or even i3 core Chromebook, it should be fast enough for chrome os as it is a light os compare to window 10. Using this laptop spec for window 10 will be much worst than chrome os. For me, if buying a new Chromebook few years later should buy a i3 core CPU to make sure the performance, as I need is speed and fast enough to open 10 or more tabs and playback 1080p with 2x speed with no lag.To conclude,Pro:light usemaximum 6-7 tabs in the same time is okCheapPremium outlook1080p 14" monCan load android apps but slowCon:Slow compare to mid range desktop.Small storage, 18.5GB onlyNo touch screen
