Computer Monitors

In looking for a new monitor, I visited Curry's and PC World for advice (ha Ha!).

All their monitors were widescreen and I was told this was the only kind available these days. Aimed at the home market. Dell only seem to have widescreen monitors.

But to my mind, a widescreen reduces the vertical visible area and most business applications are oriented this way. i.e. a Word document scrolls up and down more than side to side. So you need a high monitor rather than a wide one.

Therefore you need to buy a much bigger monitor to get the same vertical viewing size.

My first reaction is that the world is wrong and I am right. But have I missed something? Should I be buying a widescreen or what are the options?
