Windows only: Hunting down application after application to fill a new computer with your favourite software can be a pain. Free application Smart Installer Pack makes it easy.
Just download the (rather hefty) 227MB application, run it, and choose à la carte from the many popular applications contained within, from Firefox or Chrome to Picasa or GIMP to more obscure favourites like Daemon Tools (image mounter). We've seen similar tools in the past (like AppSnap), and while SIP doesn't offer as wide a feature set, it's still a decent alternative to a long Google hunt for each app. The SIP installers don't run silently, so you'll still have to hassle through all the clicking (another drawback that puts the previously mentioned apps a step ahead of SIP), but it's got an attractive, simple interface that anyone—computer savvy or not—can handle.
Smart Installer Pack is a free download, Windows only.
