Here are a few I can think of, not all are necessarily things that I miss, but people do miss it.

- Gmail old style compose/reply dialog

- Windows 7 had a search everything feature, now windows 8 has search by App/Files/Settings

- Github used to have a downloads tab for you to upload binaries associated with your code.

- Internet Explorer 9 supported extensions (via plugins), IE 10 is plugin free (although a step forward) doesn't have any customizability (no potential ad-block / vimium)

- Twitter List functionality (it wasn't implemented well but it was useful to help separate your stream).

- OneNote- Older versions of OneNote had OCR functionality, newer ones don't, one of the reasons I prefer Evernote

- Gmail's compose is different now. While you compose a message you can, check email. That's cool.

- I acknowledge that OCR functionality is very important and many products miss it.

Thnak you samir

The Compose functionality is quite nice, but not when you do mailing lists, where bottom-posting works best. The new UI makes that painful.
