Hi, I want an old iBook mainly for surfing and email, nothing too intensive. Would an iBook G3 500Mhz 640MB RAM suffice? Just how slow is that? There's one coming up on eBay with those specs that doesn't look too expensive, so I want to know if it'll be able to cope with Tiger and the new Safari? (I think it's got Panther installed currently.) Thanks for any advice.
