I have a relatively old mac (iMac Retina 5K, 27 inch Late 2014, with 4 GHz Intel Core i7, 32 GB 1600 MHz DDR3, MacOS 10.10.5 Yosemite, Evernote 6.12.3). My Evernote application interactions are painfully slow as well. Such that I'll select and start typing only to find it didn't select what I wanted and now I'm overwriting something I didn't want to. This sort of interaction breaks momentum of thought, where you have ideas and thoughts to write down but the sluggish response breaks or impedes train of thought. I attribute most of this to disk wear - my mac has an SSD which is nearly always full and thus the whole of it has been written and rewritten so much that I am certain the disk controller is constantly dealing with bad sections and fragmented data. Eventually I'll migrate to a new machine and I bet it will have snappier response rate. Kwan Heng Lee: how old is your mac?
I find that most web clips I try do not properly display. (MacOS 10.10.5 Yosemite, Evernote 6.12.3, so yeah, old mac, old OS). If its an article or page I particularly want to retain, I will do multiple clips, first full page, then simplified article, and finally a screenshot version so I can see how it was supposed to render. The screenshots nearly always get resized and distort the fonts, making it look bad though. It is increasingly frustrating. The whole purpose of this application and service for me is to save articles and information that is important or interesting to me. Yet when I revisit them, it can be hard to see why I would have clipped such a jumbled mess.
