and mobile phones about equal in the 'best gadget' stakes.
Both of them must be right up there in the 'most useful innovations' list.
I'm quite keen on photography (note the word 'keen' rather than 'good'), and having a digital camera has changed my life as far as photographic convenience is concerned. My present camera can turn out 1200 images on one battery charge if I use the battery grip. That would have meant lugging almost 3 dozen film cartons around with me in the old days.
As for my mobile phone - I struggle to think how I would manage without it now.
