No offense at all Angus! I don't believe you're getting a true OS X mini Mac like you're thinking, however. The iPhone will indeed be running a trimmed down version of OS X, like an OS X Lite, and it won't be able to be a substitute for truly having a laptop for computing work. I believe one disadvantage is not having a slide out keyboard.... The onscreen tap keyboards are not for quick entry and makes replying to emails arduous. There doesn't look to be handwriting recognition like the old Newtons. I have an iPaq 3835 without a keyboard and tapping sucked. The Cingular 8525 I have now has the slide out keyboard (Blackberry brought them back into style actually) and it beats handwriting recognition every time. I absolutely love the iPhone's screen. The 480x320 resolution will be much appreciated by every user, and I often wish my 320x240 pixel screen had more resolution and more screen space. I think web browsing on the iPhone will be top in its class. Once they get hard drives inside the iPhone, making it essentially an awesome Apple version of the Palm LifeDrive, NOW you're talking about the ability to start replacing a laptop. For those people with standard POP3/IMAP4 email accounts (i.e. not running on an Exchange server) that haven't already entered the Blackberry/GoodLink market, this device will blow you away and you'll love the on-the-go connectivity. Be prepared for a more chunky device than you are used to carrying around, but it is worth it. Also, no matter what device you own, be prepared to pay Cingular an extra $40 / month for the unlimited PDA data connectivity. That's on top of your voice charges. Oh yea... I don't care how great they claim the screen is and what types of cases are sold at launch.... slap on a membrane screen protector immediately when you open the box and replace it every 30 days. You'll be glad you did. Tom
