How does the G4 800mhz processor compare to let's say a pentium 4 1.6 GHZ?
It should hold its own in most tasks, blow away the P4 in others (i.e. Photoshop, and other applications specially optimised for the G4 chip) and get beaten in others. It's a totally different architecture, but the G4-800 is no slouch.
what is Aqua and Cocoa?
Aqua is the user interface for Mac OS X. The candy buttons, the drop shadows, that's Aqua.
Cocoa is a programming environment for OS X that uses object libraries to aid in rapid application development. Nothing really that needs to be discussed, but generally, in this point in the transition to OS X, cocoa applications have a more 'os x' look and feel to them than carbon ones do - carbon being the updated APIs from classic Mac OS.
what common utilities for the PC also have MAC versions, ie Winzip, CDR burning software, kazaa, grokster, email programs, etc?
Winzip = the Stuffit suite of products. It handles .sit, .zip, .tar, .gz, just about any format. I know Stuffit Expander comes pre-installed, but you may want to download Stuffit Lite (the whole bunch) to be able to compress files too. <a href="http://www.aladdinsys.com
CDR burning software = Depends on what you want to burn. If you're looking to burn a Data CD, you just drag the files to the disk on the desktop, and click the 'burn' button. For DVD burning data, it's the same process. To burn an Audio CD or an MP3 CD, use iTunes- apple's MP3 player/organization/burning software. Best of breed. To burn a DVD-Movie, use iDVD, which is, like all of this, included. If these tools don't work, it's probably your best bet to buy Roxio Toast: it's 99 bucks.
KaZaa and Grokster = While no KaZaa or Grokster software per se exists, there are many alternatives. For music, I use Audiogalaxy with the Sputnix satellite program (www.biggerplanet.com
For everything else, Gnutella is your best bet. The 2 best Gnutella clients are Aquisition (www.xlife.org
) and LimeWire. LimeWire is just a shittier program, though. Aquisition takes a biit of time to first connect to a bunch of servers, but once it gets something, it goes really nicely.
Email client: The included Mail application is sufficient for most needs; it does multiple accounts, filtering, HTML, pictures, etc. Beyond that, there is Eudora, Microsoft's Entourage (which is really a good client, but you have to buy Microsoft Office to get it... but Office is a good suite of applications anyway.)
How do you setup TCP/IP so that i can hook it up to my DSL router and get internet access?
I am *almost* positive that you can just plug in the Ethernet cable and OS X will auto-configure itself for the router- may be wrong, though. Not my area of expertise.
