1. It's pokey. Unless you're within range of Wi-Fi, its network connectivity is so slow it's almost unusable. The iPhone uses AT&T's EDGE network for wireless broadband connectivity, an awful choice because it either takes forever to load a Web page, or doesn't work at all.
2. Forget copying and pasting anything. One of the most powerful features of a modern operating system is still missing from the iPhone. How hard could it be to just let us copy some text from one e-mail and paste it into another, for instance?
3. Inaccessible internal battery. When you're on the road, you always want to have a spare charged battery on hand in case you run out of power and there's no outlet nearby. Couldn't there have been a unobtrusive battery door in the back of the iPhone?
4. This "unlock" nonsense. No third-party applications can be loaded onto the iPhone unless you use questionable hacks that can sometimes permanently break ("brick") the phone. Sure, Apple's opening it up to developers next month with the release of a software developers kit (SDK), but that should have been done from the start.
5. It's too hard to type on it. You can enter text quickly on the thing after some practice, but there are still way too many errors. Sure, it corrects errors on the fly, but it's not as omnipotent as Apple acolytes would have you believe. It's just not as easy to use as a hard-button keyboard, and those who say it is are so motivated to love the iPhone they'd probably put up with any hardship.
6. No AIM. Instant messaging is a killer app, and the iPhone has an SMS system with great software. However, you only get 200 of those messages free, and after that, you start paying through the nose. We'll wait for legit third-party apps for our AIM fix, but until then, it's either get ripped off or settle for third-rate hacks.
7. It's too heavy. Careful who you hand that iPhone to, because it's a lot heavier than it looks. People who aren't familiar with it will probably drop it or come close to it, so you'll need to show it off with a soft surface underneath to avoid awkward moments.
8. No Flash applications. While many web apps that use Flash are just obnoxious, there are many that are excellent. Case in point: embedded video, which you can't view on the iPhone. Yeah, YouTube is filtered to you in a walled-garden subset, but we'd like to see the whole Web, not just the flash-free parts.
9. Your old headphones don't fit. Why, oh why did Apple create a headphone jack into which only its own earbuds would fit? Stupid decision. There are aftermarket adapters that fix the problem, but why didn't Apple just do this right the first time around?
10. Lame e-mail app. Yes, it looks beautiful, better then any email application ever has on a cellphone. But why can't you at least select all the old emails and delete them as a group?
