I have my lovely new iPhone, I am indeed an Apple fanboy. While my old phone is able to do more (until Apple release the SDK in February), the usability of iPhone coupled with the unlimited internet access tariff makes it perfect for me.

I get tied into an eighteen month contract, which is fine, I'm happy to stick with a phone for that amount of time. But looking to the future also makes me look to the past.

One of my first computers was a 48K ZX Spectrum. In 1982 it cost £175 and (unsurprisingly) came with 48 Kilobytes of memory (although a chunk of it was taken up with screen memory - no 'graphics cards in those days...).

My iPhone has 8Gb of memory - this works out to be equivalent to 166666 "ZX Spectrums" of memory*. Lay them end to end and you get a line of Spectrums 38.83 Kilometres long (a shade over 24 miles). That's from my house to Southend on Sea.

It'd also cost more than £29,000,000.

1982 to 2007 is 25 years, I'm hopeful to live for another 25 years (dying before I'm 60ish would be a bit unfair methinks). So I wonder what sort of phone I'll be using then.

Until then I think I'll be eating as cheaply as possible...

(Actually my first computer was a Texas Instruments TI99/4a, but comparisons to that would be silly).

*Assuming that my maths is correct - this is no guarantee of accuracy.
