So I have a late 2006 Macbook (2.0ghz C2D, 2gb RAM, 120gb HDD) that has recently been replaced with a 2011 iMac. Since getting the iMac I've been missing some of the portability, so I've been going between 3 options: 1) Get a Macbook Air 2) Get an iPad 3) Get a new battery and SSD for the Macbook I'd mainly be using it for web browsing, skype, word processing, and MAYBE a little bit of Photoshop work. Basically something for bed/couch browsing, and the occasional library study session. So basically, would it be silly to do upgrades on a machine that's almost 5 years old? Or would getting a new machine/device just be a better choice? Notes: Wifi on the Macbook was being wonky until I did a clean install of Lion on it (don't really understand that myself) so I don't know if it's gonna crap out again, and battery life actually isn't that bad (around 2-3 hours) but the battery is bulging.
