1) No TRIM support out of the box if you are using your own SSD (not Apple's)

This is ridicolous: TRIM only seems to work for Apple buit-in SSDs. There is a tool by groths.org that will do the trick: TRIM Enabler, which works for Lion and for Snow Leopard as well. You might want to consider enabling this feature, since TRIM will make your Solid State Drive last longer, due to less writes to the cells.

2) Mouse scrolling direction got reversed: how to revert

Apple decided to reverse the mouse scolling on 10.7 Lion, meaning you have to scroll your mousewheel up to actually move the on-screen content down. Here is a screenshot from System Preferences, where you can change that "feature" to the way it was before: simply uncheck the box left to "Move content in the direction of finger movement when scrolling or navigating".

3) Disabling the "Resume" feature

The "Resume" Feature in Mac OS X Lion restores the state of the application windows, when re-opening an application. Since I definitely do not need this feature, here is a way to turn it off: just uncheck the left box next to "Restore windows when quitting and re-opening apps" in System Preferences -> General

4) Disabling "Versions" feature in Mac OSX 10.7 Lion

Versions should't be a problem unless you are using Time Machine. MacRumors has a forum post on disabling that features.

5) Other (small) annoyances

Google Chrome does not get moved with an update ( Chrome vanishes with Lion 10.7 Update)

This is also very strange: the Google Chrome Browser did not get moved on my Lion update. I had to re-download Google Chrome.app. At least the Application Support files got moved, so I did not lose any browsing history or bookmarks.

Dropbox needs to be reinstalled: special Lion build

The dropbox right-click features dissappear when updating to Lion. Download the Latest Forum Build of Dropbox that is Lion compatible (1.2.16 at the time of writing this entry)

Other interesting reviews about Mac OSX 10.7 Lion can be found here:

* Time Magazine on OSX Lion: "With OS X Lion, Apple's Macs Enter the iPad Era"
* Engadget: "Apple OS X Lion (10.7) review"

2 new Player Widgets are available. With the new "Artwork" and "Mini" Players, this makes a total of 3 available Player Widgets for SoundCloud.

While the Artwork Player is a great way to showcase album art in your SoundCloud tracks, the Minimal Player is great for embedding where there is not much space available. All in all, the two new Widget options are giving you more options on how to feature your tracks without having the usual SoundCloud look, that is the same on all sites using it (except color adaptions, which were possible before).

Stats have been totally revamped: Who, What, When, Which and Where can be found out for your Tracks now - but - depending on your account type. Full Stats are only available for Business PRO users, while the other accounts have different detail levels. The difference from the Premium SOLO to the full stats seem to be, that embedded, linked or posted tracks are not statistically tracked.

The sharing was also reworked, here's the quote from the official sendout: "Much asked for - here it is: private track sharing via secret link. Simply upload a track or set, generate a private link for it, then quickly share via email or IM. Plus with newly the added privacy options, you can now control if you want people to comment or your tracks or not, hide the stats around your track and make comments only visible to yourself. Perfect for when you're doing promo or need to keep the number of recipients private."

Finally, there are 2 Desktop uploading apps available as of today: "Scup and CloudPost are two nice little apps that let you upload your tracks and sets to SoundCloud right from your desktop". And "one more thing": the iPhone App for SoundCloud which can be downloaded for €0,79 or $0,99. Detailed reviews of all the apps right after I tested them.

Cheers and happy uploading.
