Fixing the 10 Things that Suck
There is a comprehensive list of iPad problems that will likely be largely fixed with software and might actually show up later on the existing iPad. But they will undoubtedly be addressed by the next version.
Of the list the inability to hover and HTML rendering issues are likely the most annoying and will get addressed first. I’m surprised they didn’t initially do stereo sound given the price of this thing but expect that will be in the next hardware and while it will likely never render Flash, it sure could deal with it a lot better.
