Polarizing filter

[DarkMatter]

The recent UV filter thread, which several people advised against the use of such filters, has prompted me to ask the following.

Back in the pre-digital age I used a polarizing filter to give the fluffy white cloud effect and to reduce reflections from glass and water. Do people still use these filters with their digital cameras or are there camera/computer software tricks to give the same effect?

Thx.

Thank you all for your comments, it looks like I can carry on using my polarizing filter where appropriate.
