Lion is still available from Apple. You will have to call Apple Customer Care 1-800-692-7753 or 1-800-676-2775. to purchase it. Then within 3 days you will get an email with a code which you can use to download Lion from the App Store. The price is $19.99
You must have at least a Late 2006 model 2,1 MacBook.
Lion will require at least 2gb of RAM but really needs 4gb to run smoothly.
As for third party programs see this list for compatibility with 10.7 http://roaringapps.com/apps:table
Also Lion doesn't run any Power PC programs. To see if you have any Power PC programs go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up select Applications under Software. Then look under Kind to see if any of your applications are listed as Power PC. Universal and Intel will run under Lion.
Before Mac switched to Intel processors in 2006 they used Power PC processors from 1994 to 2005. Power PC 601 through 604, G3, G4 and G5. Applications written for the Power PC processors need the application called Rosetta to run on Intel processors. This was part of the Operating System in 10.4 and 10.5 but was an optional install in 10.6. With 10.7 Lion Apple dropped all support for Power PC applications.

Thanks! This is very helpful.
I have the MacBook 2,3 which I believe is late 2007.
I am currently running Snow Leopard OS X 10..6.8 and I upgraded to a 500GB Hard Drive, and I added 6GB SDRAM memory.
I am hoping to be able to transition to lion as to run the latest iMovie software. Unfortunately, I don't think I will qualify for the Mountain Lion operating system though.
I have the 2.2GHz Intel Core 2 Duo processor.

I noticed extremely few Power PC applications that were there. Mostly Intel and Universal.

You only have to worry about third party Power PC programs like Adobe CS2 or Microsoft Office for Mac 2004. Any Apple programs will update to Intel when you upgrade to Lion.
