I really want to ditch this PC laptop and dive headfirst into the mac world. I've been flip flopping between wanting a macbook/macbook pro/powerbook for a while now and I'm getting seriously feed up with myself. The problem is that i cant really justify spending upwards of $1000 for a new computer when my current one works fairly well (for windows). So I think an old school powerbook might be the answer I'm looking for. I've seen them go for $300-400 on ebay and just want a confirmation that this will be fast enough. I only plan to use it for internet, music, the iLife package type things, no games, no photoshop. But I want to make sure that it'll do these good enough to leave me with a good impression of OSX. So what do you think? Still a very capable machine? I've also seen powerbooks with both leopard and tiger. which is better for me? more features of leopard or better performance of tiger? anything i should look out for when buying a 5 year old machine? It's also very likely that i would put this back on eBay after 2-3 months and get a new macbook/pro if i fall for OSX. Advice?
