iPad vs iPad 2: Safari RAM Tab Test

Why has his screen on his iPad gone all yellow?, is it just different brightness settings or do all iPad screens take on that sickly yellow tint over time.
I noticed this at first as well and just figured he maybe has a screen protector on it like Invis Shield or something...
Probably has 4.3. I installed 4.3 on my ipad 1 and it got noticeabley faster but didn't affect reload or checkboard effect. The reason why i sold my ipad was that would bug the hell out of me but the ipad2 seems to be doing well with it.
I notice that if you have mutiple tabs opened, with at least one that is still loading in the background, you get checkerboard effect even if the tab that you are looking at has already been fully loaded. But once all the tabs are fully loaded, no matter how fast I scroll up and down, I don't get any checkerboard,
The checkerboard effect hass more to do with the CPU rather than memory. When there are other tabs loading in the background, lots of processing power is devoted to those tabs, and the remaining processing power is not enough to generate the content quick enough and avoid the checkerboards completely. That being said, the A5 is really a top of the class SoC for this class of devices, and the checkerboards go away noticeably faster than on the iPad 1.
I'm surprised that background tabs take a lot of CPU power, there's no real need to do any formatting until the user looks at a tab, but maybe Safari does some basic syntax checking and pre-formatting of the elements in the background so that when they do get put in the foreground they display more quickly because a lot of the processing needed to render is already done. Despite my confusion about why background tabs in the process of downloading suck up so much CPU power, I'm still inclined to agree with your analysis.
If you are right then this seems to me to be something that could be fixed, or at least improved, with a software update. It's really down to thread priorities, maybe the thread(s) working on the foreground display should get more of the available CPU when the user starts scrolling the foreground page at the expense of temporarily diverting CPU cycles away from the thread(s) that are doing the parsing (or whatever else they're doing) of background tabs being downloaded.

I agree browser loading is now amazing wooot all my complaints of iPad 1 are fixed with iPad 2 are fixed except multitask gestures and notifications ios5 hurry up hehe
Multitouch possible
Multitouch gestures can be used with 4.3. You will need to install Xcode and complete a few steps. You will then have the option in settings. Google it and you'll find numerous step-by-step guides. I love it!
