God you luddites are boring
Queue the DV's but mention smartphones in these forums and the same tired old "my phone is now 5 years old and it's great" mantras and told-you-so's come ringing out.
No I do not need or want a removable battery, or an audio jack, or 48 hours talk time (Kee-rist : only a tiny portion of time on a smartphone is talking to somebody) or a bleeding keyboard. I could happily live without any phone but I choose not to. A great deal of stuff is far easier today than it was 5 or even 2 years ago. OR a lot more stuff can be done from what's in your pocket than 5 or even 2 years ago.
Trite example but time was it was a complete p-in-the-a to have to take 2 minutes firing up a microwave oven-size computer just to check the frigging email. Now my pocket gives me a gentle nudge when one arrives. Magic!
Nor do I have to look anxiously at my watch (in fact the phone time is more accurate) while in a rush to get to the office and a desktop to review an important document since I can look at it on a (very high quality) screen a few inches square.
I do not need to go to the bank, visit HMV, consult the yellow pages, or call directory enquiries, ever. I never need to carry an A to Z. I do not need to squash into the corner seat of the 8:13 to Paddington to open awkwardly the cartoon page of the Daily Telegraph (or Hustler, or -yes!- this very forum! Woweee....).
I could go on, and on. It will get only better and I do not believe there is a plateau - except possibly in absolute growth, for the reason which is the one and only partly correct statement made hereinabove, i.e. that most smartphone customers already have (a fairly new) one, amongst a mountain of bollocks.
