iBooks is solid and the loading of large volumes is improved significantly enough to make it worth noting [I'm talking 1000 page+ documents].

Running under Firefox 10 takes more time on my Linux workstation which has a lot more raw power.
Out of 176 applications installed I have only seen a couple dozen updates after the release of iOS 5.1. I expect to be buried with updates in the next couple of weeks.
Thanks for the detailed response. Looks like I need to update "my" iPad 1, once I find a chance to prior it out of my wife's hands...
I am, however, happy to report that battery life on my iPhone 3GS is greatly improved with the upgrade to 5.1 - yesterday with 12 hrs of standby (wi-fi was turned on, but not connected to any hotspots) the battery indicator dropped by only 27%. Prior to the update I was getting around 3%-4%/hr battery drop in the same non-usage scenario (the update to 4.1.2 or was it 4.2.1 really messed up the battery life).
As for my wife's iPhone 4, I'm not sure but my wife hasn't complained so I assume things are going well. With 5.0.0/5.0.1 she was running into a weird problem where the phone would "hang" on incoming calls (wouldn't be able to answer the call) and would also stop receiving SMS when data was switched off, hopefully this is resolved with 5.1.
