I have always pre-ordered Apple / Mac OS X so that I could install on the release date. It was exciting to get the package in the mail, fire up the Mac(s) and start the installation. With Lion, it is an all digital / online upgrade from the App Store. This is the first time Apple has offered a new OS as a download rather than a box and disc.
With the OS being an install from the internet /App store, I was very hesitant to upgrade right away. A few weeks after the release, I decided to upgrade my 5 year-old MacBook to Lion. All went smooth for the install, no freezes or issues at all. For this OS and the last, Apple has only charged $30 to upgrade, rather than $130. : )
After testing on my laptop for about a month, I was confident to upgrade my 27″iMac, which is my main work station. For the most part, Lion is a great improvement, though I do have a few complaints…
Power PC applications are no longer supported. This means I can no longer run my Microsoft Office 2003 Suite. It is probably time to upgrade my MS Office Suite anyways, and I do understand that Apple would need to drop Power PC support at some point, to keep the OS efficient. Overall this is more of an improvement and not so much a complaint, rather just and annoyance for now.
The only other issue I have with Lion is that Mission Control has replaced Expose and has not impressed me at all and in fact slowed down my work process a bit. In Expose, you could see all of your “spaces / desktops” and drag windows between any of them. Now in Mission Control, you can only drag from the last desktop you were on, to others, not from any desktop to any other desktop. This has been quite a downgrade in my opinion.
Launchpad is a nice feature, copied from iOS and also the built in Facetime App is much appreciated. Over all, I would say the $30 upgrade is worth it, though the Mission Control needs much improvement.
