So yes, the iPhone is amazing. But no, it’s not perfect.

There’s no memory-card slot, no chat program, no voice dialing. You can’t install new programs from anyone but Apple; other companies can create only iPhone-tailored mini-programs on the Web. The browser can’t handle Java or Flash, which deprives you of millions of Web videos.

Pogues Review of the iPhone The two-megapixel camera takes great photos, provided the subject is motionless and well lighted (samples are at nytimes.com/tech). But it can’t capture video. And you can’t send picture messages (called MMS) to other cellphones.

Apple says that the battery starts to lose capacity after 300 or 400 charges. Eventually, you’ll have to send the phone to Apple for battery replacement, much as you do now with an iPod, for a fee.

Then there’s the small matter of typing. Tapping the skinny little virtual keys on the screen is frustrating, especially at first.

Two things make the job tolerable. First, some very smart software offers to complete words for you, and, when you tap the wrong letter, figures out what word you intended. In both cases, tapping the Space bar accepts its suggestion.

Second, the instructional leaflet encourages you to “trust” the keyboard (or, as a product manager jokingly put it, to “use the Force”). It sounds like new-age baloney, but it works; once you stop stressing about each individual letter and just plow ahead, speed and accuracy pick up considerably.
