No surprise here: Apple delivered another pitch-perfect keynote at WWDC 2011. Jobs & Co.’s first address since the iPad 2 announcement unveiled loads of details on Lion and tantalizing looks at iOS 5 and iCloud, mixing the expected and the unexpected in a way that made the day’s wealth of news both satisfying and surprising.

I wondered, though, how many of the developers in the audience were less enthusiastic. Many of the new features in iOS 5 build the functionality of some of the most popular apps right into iOS. To-do lists, photo uploading, group messaging, and loads more will be baked into your iDevice. That means most users will have to be dissatisfied with Apple’s version before venturing into the App Store to consider purchasing popular, successful apps like Things, CameraSync, and more. Pardon this devil’s-advocate thought… but was the App Store just an idea farm for iOS updates?

As an end user, though, it’s hard to be anything but delighted that Apple’s putting so much value into its products. That only attracts a larger installed base, and the challenge to developers now is to capitalize on that bigger audience with bold new apps.

Overall, I’m pretty thrilled about Apple’s plans—whether it’s little details like Auto Save and AirDrop in Lion or huge new iOS 5 features like Notification Center and Reminders, the next few months will represent big steps into the future of our Apple gear. On the flip side, I do have one major worry: bandwidth. It goes without saying that the U.S. is hardly a leader in broadband penetration—many homes are still stuck on dial-up or other slow options like satellite. On the wireless side, AT&T and Verizon still seem to be staggered by the demand for 3G service in urban areas (and are refusing to offer unlimited data plans to new customers, to boot)—to the point where I have my doubts about how effectively or quickly the 4G future will really arrive.

So Apple’s decision to push into the cloud with both iCloud and its online-only sales plan for Lion definitely gives me pause. After all, I live in the San Francisco Bay Area, and I’d rather upgrade to Lion with a disc instead of waiting the hours it’ll take me to download the 4GB Lion update. What about folks with no broadband?

As far as iCloud goes, I’ve been burned by MobileMe’s unsteady performance too many times, so I’ll be moving very gingerly into that cloud. But more urgently, are carriers really ready for this massive uptick in traffic? What’s going to happen when we’re all trying to beam our music, calendars, app purchases, and more around on 3G? Sure, many of us are on Wi-Fi for at least part of the day, and I hope even more now that the next iPhone supports 4G… but I have to think AT&T and Verizon blanched at the iCloud news. Here’s hoping that if demand for iCloud shoots through the roof, that’ll be the final nudge that U.S. carriers and ISPs need to invest in wireless and/or wired broadband everywhere.

So now it’s your turn. What excites you--and what worries you--about iOS 5, iCloud, and Lion? Drop me a line.
