Attempting to review a device with the dizzying profile of the iPhone is oddly bemusing; it means different things to different people, and in the end, it depends what you want or expect to get out of it. To use it only as a phone is a bit like living in the Taj Mahal when all you really need is a tent. I''ve only had the iPhone for three days, and it''s my first. This review will therefore be from a new-user''s point of view and without reference to the competition. In other words, what it''s like to live with an iPhone 5s.The presentation of the phone, with its exquisite Zen-like packaging, builds the anticipation, until finally the waiting''s over and there it is: looking and feeling like a bar of gold or precious metal, its solidity and weight are somehow reassuring. The harmony in the architectonics is a triumph of aesthetics, and that''s without even switching it on. But before you do that, you''ll be required to fit your nano sim card. Using the pin supplied, this requires the dexterity and sensitivity of a concert pianist matched with the optical facility of an eagle, but once done you''re ready to fire it up.If you already have other Apple devices you''ll find your phone exchanging data straightaway, with your contacts, photos etc being ported over the airwaves. There''s relatively little to do in the way of set-up as most of it appears to happen automatically. You can then personalise the phone even further, first with the famous finger-print. This involves (as does so much from now on) in going into Settings. Choose Touch ID and after rolling your digit around on the Home button, the sensor registers your details, and from then on opening up the screen is quick and easy, plus you can use it in the ITunes store. If you can''t decide whether you''ll be using your finger or your thumb then why not register both, and if you want to allow anyone else access to the phone then they can add their fingerprint too. An extra precaution of a numerical passcode is required to access your credit card information. Once set, this also transfers to other devices, meaning you never have to manually fill in an internet payment form again.I have the 16GB model, and possibly some juggling might be required in deleting and later re-loading apps/photos/downloaded songs on Spotify, but that doesn''t look as though it''ll be a problem for some time, as at the moment there''s 11GB free. What might be an issue however is data allowance from your provider; I seem to have got through 100MB already, and that''s only in a couple of days. It might be best then to choose a contract with an unlimited data allowance if you are going to want to make the most of the iPhone''s entertainment value.Navigating around the phone is intuitive enough, the Home button being the key to changing between apps. Double-click this and it will bring up all of your open applications, which is often a clearer way of orienting yourself. A swipe upwards reveals the torch (which is very powerful), the calculator, the timer and camera, as well as Wi-Fi, Bluetooth, Do Not Disturb shortcuts, plus your music player. A downward swipe within an app displays your schedule. A downward swipe on the Homescreen brings up the search facility, which can be used with confidence. Siri, the slightly surreal footman character can be activated by bringing the phone up to your ear. Using its mystifying powers, Siri can then find the way to the nearest Tandoori or be grilled for the sum of 4.3339 + 2.7, its seemingly inexhaustible knowledge providing hours of amusement. If Siri can''t solve your problem directly it''ll find references on the web which should provide you with an answer.YouTube and iPlayer are rendered in a crystalline clarity and the dimensions of the 5s give a panoramic quality to the theatre. The sound is remarkably full, and the earphones supplied seem excellent. Photos are catalogued in Years, drilling down to Collections and then Moments which sounds overly complicated but is actually coherent in use and quick to comprehend. The quality as you''d expect, is uniformly excellent and the new flash arrangement leads to an enhanced quality in poor light.From then on the sky really does seem to be the limit, with apps for just about every conceivable occasion. In short, the iPhone is a device which you possibly never knew you needed, but once you''ve lived with it for a few hours, it''s hard to imagine life without.
