For some people this is a major issue. For me, since I usually either have a PC on and can trail a USB cable, or Laptop Accessories spend the day driving with the iPhone hooked up as an iPod and being charged by the car, it is less of a constraint. But it remains an annoyance. I haven't yet seen an iPhone equivalent of the Dell Latitude "Slice" - a battery "back pack" for the iPhone that could more than double autonomy with minimal extra thickness, but I assume that someone, somewhere, is working on an aftermarket device.

7. Document management
There is no equivalent of the Windows Mobile File Manager or Mac Finder on the iPhone so there is no Dell Inspiron E1705 keyboard way of manipulating file objects on device.

Admittedly the iPhone does a credible job of shielding you from the need to do any file level manipulation: For example the Camera has a photo album that is also Toshiba PA-1650-01 AC Adapter accessible in other applications that need to access images (for example, the iBlogger application I use to write short articles on this site). But there are still occasions when you need to manipulate individual file objects.

One is during installation and set up when installing root certificates for SSL so that the device can talk to an Exchange server: Unless you use Apple's enterprise deployment tool (which locks down the device and prevents further configuration changes, so not always desirable), the only ways to set up the device for Exchange are to set up a temporary IMAP account and download an attachment that you open, or to set Toshiba PA3467U-1ACA AC Adapter up a website with the root certificate and define the appropriate MIME types on the web server (I could not get this to work, incidentally!). How much easier it would be to download the certificate onto the device using Windows explorer (connecting to a PC via USB exposes the devices memory as an attached storage device) and to be able to open the certificate file from memory on the iPhone.

The other key need for this functionality is when manipulating attachments on email messages. There is no way of saving attachments, or attaching documents selectively to a new or forwarded message.

6. Navigating through email folders
I tend to keep a lot of 15.4 inch LP154W01 LCD Screen emails in my mailbox. I archive once a year, and usually towards the end of the following year. I'm also fairly busy and work on a dozen consulting and business development projects at a time. That means two things: a lot of emails, and the need to organise those emails sensibly.

I organise my emails into trees - consulting projects in separate folders and these folders organised by client, all kept separate from companies I'm invested in and from my personal stuff. Probably 40 or 50 folders.

On Windows Mobile devices I can organise this quite cleanly, with the ability to expand or collapse sections of the folder tree. The iPhone recognises the tree, but gives me no means of collapsing the hierarchy. The Inbox is always at the top: Junk email is always at the bottom. Moving incorrectly junked emails means traversing the whole tree, which is a pain even using the classy flick scroll gesture. It's clumbsy and unnecessary.

5. Filtering offline email content
The other side of this complexity is managing how much of my "online archive" to take with me.

There is no need (and no space) to take it all with me: I am quite used to placing sensible limits on the section of the mail folder to take with me. Windows Mobile allows me to take 1, 2 or 3 months worth of email with me, to say whether I take attachments with me, all the email or just the headers. I can even select which folders to take or leave behind. And I don't need to worry if I go away and find I am missing a crucial folder - I can change the parameters and the device will download what's missing.

8. Onscreen keyboard
One of the things that strikes you about the iPhone is the absence of any keyboard or stylus. Delta PA-1650-02 AC Adapter In fact it's almost devoid of buttons altogether, which is one of the criticisms I would level against the iPhone.

The absence of a keyboard was one of the reasons I delayed switching to the iPhone in the first place. I work out of the office probably 60% of the time and my PDA is often my only link with my business while I am out of the office. Sending email via a T9 keypad is not ideal, and most soft keyboards I have see to Original Compaq Presario M2010US AC Adapter date have been frustratingly slow. I have had a couple of PDAs with slide-out keyboards and these can be satisfactory, but they also make the device heavier, thicker and less attractive as a telephone handset.

The iPhone soft keypad is surprisingly good. I watched some demos on YouTube before I ordered the iPhone yet had nagging doubts about how realistic they were. I need not have been concerned, however: It really is as good as the demos suggest. The auto-correction works by comparing what you type with the keys around the key you strike, so if you hit an "h" instead of a "g" it will pick this up and correct your mistake.

It isn't perfect, however. I have consistent problems reaching the space bar and seem to hit the letter "b" instead. The correction picks up faulty key presses, but won't necessarily correct a mis-spelling if you put too many or too few letters into the word. You also need to be around 60-70% accurate with your key presses or the algorithm gives up. Rejecting an auto-correction Dell Latitude D620 AC Adapter suggestion requires that you hit the miniscule "x" at the end of the suggestion, rather than a dedicated key or backspace as in most Windows applications, and this can be really difficult.

But overall the keyboard works well and, I have to admit, is more usable than the keypads on most of the Windows Mobile PDAs I have had. I'm still not sure whether I prefer it to handwriting recognition with a stylus, but I can live with it.

7. iPod on a phone
Although it lacks the intuitive touch wheel interface of the original and best iPod, the iPhone, like the iTouch, Toshiba PA3467U-1ACA AC Adapter makes up for it with its full screen iPod player interface that gives you faster and more direct access to media stored on the device. I prefer the wheel of the iPod, but I admit it's 6 of one and half a dozen of the other.
