I bought my very first computer in January 2007 and had decided on a Mac computer since Macs are known for outstanding graphics features that are useful for photographers and artists. The beauty of Mac computers is that they have no "towers"...everything is built into the monitor itself, and that includes being able to playback and/or burn DVD/CDs. One can even create movies, slideshows on this computer.
Since this is the "old" Tiger version, it predates the newer "Leopard" version that only came out a little while ago
Another great thing about Mac computers...while they are out there, Mac computers are less likely to be affected by viruses
The downside ....The Mac word processing system, which is Text Edit and Pages, does not match Microsoft Word...for that one has to download/buy a Mac compatible version of Office Word--also Macs browser is Safari, which also has limitations and often one can't open up certain websites with it...A recommendation is to download the free Firefox browser
If one is used to PCs which I learned on, it does take a bit of doing to get used to MACs...there is NO right clicking abilities..one has to compensate and know which key and left click for certain functions...even the keyboard it a bit different.
But all in all, I recommend a MAC computer hands down over PCs anyday!
