A few facts about the 360.
The Core: $279.99
Most people call this the tard pack. It has no headset for talking over Xbox Live, no Ethernet network cable, no wireless controller, no memory card or hard drive and no HDMI ports. MS is supposedly going to relaunch the Core later this year with a free memory card and 5 Xbox Live games.
The Pro: $349.99
I'd wager most people buy this version. Includes:
A hard drive (20 gig), headphones for Xbox Live, Ethernet cable, AV Cable - Standard/HD and a wireless controller instead of the wired in the Core version.
All the people I know have bought a hard drive sooner or later if they bought the Core first, save yourself the money in the long haul and get the Pro instead the Core.
The hard drive is needed if you have lots of Xbox Live games, you want to download movies, music, etc or play Xbox games from last generation. The hard drive is also used in some games to cache data for faster loading. (Side note: All future made Pro's are supposed to come with HDMI standard)
The Elite: $449.99
Everything you get in the Pro and then some. The Elite's major selling points now are a bigger hard drive (120 gig), HDMI (the Elite is the only version to ship with HDMI cables in the box) and a 2nd built in heat sink on most of the systems (check the lot numbers.)
Halo S.E.: $399.99
Same as the Elite but with a new paint job, the
Play & Charge Kit for your wireless controller and a smaller 20 gig hard drive. Some of these SKUs have the 65nm chips.
Extra Info
All the launch consoles had 1 heat sink and the 90nm core chip.
Later, Elites were launched with the 90nm and 2 heat sinks to counter act what most considered the cause of the RROD issues.
The new Halo S.E. is supposedly the first console to have the new Falcon 65nm chips. However, it's not across the board yet. MS will eventually have all consoles with the 65nm chips.
Check your lot numbers. I'd post them, but MS is stealth launching the Falcon so I haven't seen 100% proof which Lot numbers have the 90nm chips & 2 heat sinks or the 65nm chips.
