"Scriptno" is very good
What are the graphics like on a mac?
Depends on the use. For gaming macs are not very good, limited choice still and gaming hardware extremely pricey. Then again for office or home recreational use it's excellent. Apps are super easy to use and generally very high quality especially when looking at value. Excellent presentation software, hobby etc. apps for next to nothing and some even bundled in. The iLife package with music sequencer, photo editor, web page maker and video editor software is amazing value for money. Then there's the ease of use - you can plug a Mac to your bluetooth amplifier with a couple clicks for example where with windows you need to replace the whole bluetooth stack with a paid version.
So far the amount of malware and viruses is also next to nothing. But that may change in the future.
