Oh man, I remember these two being particularly brutal. Anyone remember the checkerboard when scrolling on the web? If you would scroll a bit too fast (and in reality it was not very fast) the website would just disappear and you'd get a checkerboard pattern until it could load more of the website into RAM. I also remember trying to fill out some forms online and it would often reload the page if you switched to another tab to check something, losing all the form data you typed in. This included sites like MacRumors when making a post. Even when they moved to 256GB RAM on the 3GS and copy/paste came out, every time I would switch tabs when writing on MacRumors I would copy all the text I had just typed before switching just in case the tab reloaded, which still happened sometimes. This was back before MacRumors was updated to try to save your post draft as you type.
