4gb of ram… that’s rough… but if you spend $15 to put 8gb in it, you can stick windows on it, spend a whole day rummaging through the settings turning everything off, load itunes and use it as a media server, backup coordinator & print server. Though OS X becomes useless after a few years, thankfully intel macs have the added value of opportunistic Microsoft being responsible, taking over and offering a fully supported OS, security updates and all, long after Apple loses interest in supporting their own hardware & customers.
