As Scorpius said, that's the price of progress. While the "full desktop experience" (including Flash) is (was) one of the main high points of the device web developers nowadays don't really consider performance on a 600MHz Cortex A8 with 256MB RAM when they design their websites, they are more concerned with how much data they can pump through our boadband/3G/4G pipes for a "rich" web experience.

The main culprits are extensive use of complex JS and large amounts of images (stored uncompressed in RAM) ensuring that our poor little mini-computers will start swapping vigorously when opening one too many tabs (where "too many" >= 1).

Case in point, just now Engadget needed more than 30s to load on MicroB, while with Lynx it didn't even take 3s.

But who needs pictures anyways? Use your imagination, kid! Why when I was a young lad "setting up a highres desktop image" consisted of placing stacks of punch cards on our desks and that how we liked it! (...)

Seriously though, it can get rather frustrating, up to the point where I actually load up mobile versions (heresy, I know..) or even RSS feeds of websites..
