Macbook 2.1 Ghz, Intel 2 Duo ---> OSX Lion. Should you?
The answer is no and here's why.
First of you must have OS X Snow Leopard 10.6.7 to go to OSX Lion.
Next, you will need a minimum of 2 Gigs of RAM for the App Store to allow you to down it. If you are upping from two 512 Megs RAM Modules that will probably cost you about $40 - $50.00. It's easy to put in and there are tons of videos on YouTube to show you how. If you are upping RAM you will instantly notice the speed increase without OSX Lion and you may want to note how good your MacBook runs and leave it there. If you are intrigued, the download of OSX Lion (10.7) will cost you $29.99. Not bad but ...
Here's what you will NOT be getting.
Most of the cool and tempting multi-touch trackpad gestures that make Lion so attractive. The multi-finger swipes/commands, zoom pinches and twirls will NOT work with the MacBook touchpad. You could set up a new Apple Magic TouchPad but what's the point? Two trackpads and a lot of money are just not worth it.
Once you down Lion you will notice how many PowerPC applications will not work. There is no fix for this as they are no longer supported. That means earlier versions of big applications like Photoshop, Dreamweaver etc. are no longer functional.
AirDrop, to me, the best features to OSX Lion will not be loaded. The ability to drag and drop to share to anyone wirelessly just won't work on the MacBook via airDrop and that's a real shame.
LaunchPad is cool-ish. If you have an Iphone or Ipad you will be used to the ability to scroll through your Apps using the IOS sideways wiping method but so what? If your MacBook had a touch screen then that would make sense. If you own an Iphone/Ipad but are moving from a PC to Mac then this would make you feel secure but why would anyone think this is a great feature if you already use the Dock. It's just as easy, if not more accessable now that you cannot finger scroll up to launch the LaunchPad.
The cool feature of holding down a letter on he keyboard for options a la iPhone won't work either. As far as I can see neither does AutoSave (sheesh) and thusly Versions are nowhere to be seen in most apps if at all on a MacBook.
Mission Control? If you use Dashboard or want to organize a lot of desktops then sure but it's not the best way to a big enough draw.
Expect your MacBook to be running red hot, like 50º and up. Your fan will be working over time but I find this is usually if the Finder window is open. Once shut it cools down a lot.
If you do buy it and don't like it enough, good luck downgrading back to Snow Leopard (unless you partitioned) unless you wish to do a clean install, inwhich you wasted $29.99
