When I initially installed Lion I was very impressed by the new features. Now, and after I have been using it for a week now, I not that impressed anymore. I think there is room for improvements:
* Launchpad: The idea is good but the implementation could be much better. You should make launchpad behave like a computer application and not like an iPad one! Right click should offer context menu to create new folders, rename and delete folders. Right clicking on an app should offer options to move it to an existing folder, or create a new one. Launchpad should also have the option not to run in full screen mode! In its current incarnation I am not going to be using it. I still prefer Spotlight for running apps. For organizing them I still prefer the apps folder on the dock.
* Full screen mode: A good idea that works very well if you have small screens or/and resolution. On my ACD I have so much space that for most apps, full screen mode is an overkill. I don't see me using it a lot. Maybe when Aperture gets it I will use it.
* Mission Control: This one I like. It combines spaces and expose very nice.
* Mail.app: The new layout is nice but I would like to see some new features regarding Exchange Server. More compatibility to Exchange would be nice. Support for Out of Office messages, categories and Exchange tasks are essential.
* Saving the state of apps: It does take a while to get used to the fact that the state of all apps is always being saved on exit. I would prefer to have the option (without using the Alt key) to not save the state of an app by default. There are situations you don't want to have an app resume its state. Imagine showing a video to someone. You close quicktime and then after a while you need quicktime again. You open it and the video resumes...Not very good!
* Finder: I prefer to have the devices on top on the left side of Finder and not on the bottom. There should be an option to change that.
