Well, yeah. You CAN get by with Earth Web.....but it's considerably slower on equivalent hardware, and far more resource intensive. For a given CPU, the Google Earth app will always be much more responsive; you don't get all that fancy 'tourist'-type information, for one thing.....and it's this that appears to make the online version so sluggish.
But of course, at the end of the day, it's a personal decision. I know that, for ME, the Google Earth app works far better. With my set-up, Earth Web is quite 'laggy' & 'sluggish'.....even under Puppy, and even with buckets of RAM along with a discrete GPU.
=====================================
Y'know, now that I think about it, on the big HP desktop rig, this might just have summat to do with the 6-yr old Pentium G5400's lack of the AVX instruction set. The 'new' Latitude's considerably older Core i5-3340m, however, does have AVX. I'll have to try Earth4Web - in Chrome itself - on the Lat.....and see what happens. It strikes me that, with the way Earth4Web works, vector extensions would be a very useful addition for the CPU. Hmm. Let's see what transpires, shall we..?
