<p>Let's a take a look at several areas of interest...</p>
<p>Stability and resource usage:</p>
<p>-Vista is a resource hog, requiring a computer w/ a gigabyte of memory and a min. 1 GHz processor, and a minimum of 15 GB hard disk space!
-Mac OS X 10.4 requires a Power PC G3 (it can run on a system 4-5 years old!) with 3 GB hard disk space and 256 MB ram
-Overall, OS X simply places less strain on the processor, so it runs both more quickly AND with more stability!</p>
<p>Ease of use:</p>
<p>-Vista tends to give unnecessary information (i.e., "Logic Tech USB Mouse Plugged In") as well as provide excessive dialogue boxes for network errors
-Mac OS X gives information when necessary but avoids supplying endless streams of dialogue boxes</p>
<p>-Vista is attempting to make progress toward a unified interface; however, it still has not reached the level of unification of all menus that OS X has had for years!
-For this reason, one must learn Windows programs individually, whereas Apple has strict protocols placed on Mac programs requiring that common menu options (such as "save", "preferences", "help", and the "about" options) appear in specified places in all programs, making people more productive with OS X--AND OS X programs actually adhere to these standards!</p>
<p>-You mentioned that "OS X had not changed much"--one reason you might think this is because Apple keeps its changes functional instead of doing things like changing the color of the START button to green and adding additional "themes" to Windows 2000 and renaming it Windows XP a year later! (You DO realize that's most of what XP was, right?!) By not doing this, Apple has maintained much better consistency of the interface (increasing productivity) and been far more innovative and introducing new (functional) features into its OS.</p>
<p>*Interesting features *</p>
<p>-While Vista still requires use of directories or the standard Start|Search functionality to find files, OS X allows one to use "Spotlight"--a blue circle w/ a magnifying glass in the upper right hand of the screen that allows one to type in a file name or contents of a file which have been continuously indexed in the background by OS X and instantly the file(s) you need are brought up</p>
<p>-Vista introduces a "new" feature Microsoft is quite excited about known as Gadgets...too bad it's been in OS X for the last 2 years!</p>
<p>-OS X includes Garage Band--basically a stripped-down version of the professional industry standard music notation and audio recording/editing suite Logic Pro ($1000)--Windows includes... Microsoft Sound Recorder?</p>
<p>-OS X includes iMovie (a video editing package), Vista includes...oh wait....nevermind.</p>
<p>-OS X also includes such programs as Photo Booth</p>
<p>-OS X natively supports such free alternative applications to expensive applications as Open Office (a fully compatible alternative to Microsoft Office), Gimp (a free, pro-level alternative to Adobe Photo Shop) and many others (including a desktop publishing suite and a 3D graphics modeling suite)</p>
<p>Security: "User Access Control"</p>
<p>-One of Vista's biggest highlights is its "User Access Control" (UAC) security, in which it prevents changes to system-critical files and settings without the user's approval. The idea behind this is to match OS X and some Linux distros' feature of authenticating the user before making system critical changes. Unfortunately, Microsoft forgot that to fully protect the system through "authentication" it needs to ask a password! For this reason, the OS X model is still far more effective as it prompts the user for their password, which reminds them that this is NOT just another "happy clicking" dialogue (in other words, that they actually need to read the message before entering their password)!</p>
<p>-Additionally, Vista's UAC tends to give general warnings like "This program may alter system files, are you sure you would like to continue?" whereas OS X gives some important pieces of information--the program requesting the action (i.e., is it Internet Explorer or System Preferences or some random game that wants to open that file?) and the actual name of the right/priviledge (i.e., System Preferences: Wireless Card: IP Address)--whereas, in Vista, the information given is simply a criptic string of numbers (a GID).</p>
<p>-When Vista gives a UAC dialogue box, the system is locked down until you confirm or deny access, so if Internet Explorer needs access to something while you're taking notes in class, you will be unable to take any more notes until you've decided whether to give it access! In the OS X version, this is not an issue, as OS X will allow you to continue working in any program other than the one requesting permission.</p>
<p>** Security **</p>
<p>-Vista is based on an NT security model and still tends to fall quite sure due to this model</p>
<p>-As it is ultimately based on a UNIX model OS, OS X has the upper hand when it comes to security</p>
<p>-Vista systems use the (potentially quite dangerous) Administrator account by default</p>
<p>-OS X <em>disables</em> the root (equivalent to the Administrator) account by default--and intentionally makes it fairly difficult to reenable (unless you are a UNIX buff--in which case, you know the potential problems you could cause as root!)</p>
<p>-Since OS X disables root by default, it has "Administrator"-level accounts that can "SUDO" into the root account by entering their password when they need to make system changes that are protected from standard users</p>
<p>-When logged in as an Administrator in Vista, you are capable of destroying the system with just the wrong click; additionally, this means a virus unleashed via a Vista Administrator account has full access to the system--whereas, the "SuDo-Root" model of OS X means even a virus unleashed via an OS X Administrator account still does not have full access to the system! (The lack of asking for a password in the UAC dialogue of Vista means a malicious program could still bypass the Windows UAC system fairly easily)</p>
<p>** Some new features for OS X 10.5 Leopard -- due out this year **</p>
<p>-iChat--Apple's Chat software (compatible with a number of protocols, including AOL Instant Messenger) supports screen sharing over IM as well as the ability to have "video backdrops"--allowing you to make yourself look like you're chatting on a roller coaster</p>
<p>-Time Machine--roll back ANY file (i.e., documents, etc.) on your computer to ANY date</p>
<p>-Spaces--multiple desktops (in case you have too many windows open at once and need to clear stuff out--less clutter!)--for example, you could use this for multi-tasking (i.e., have one desktop for gaming, another for notes, and another for the paper you have to get done!)</p>
<p>-iCal will now have full support for keeping track of all your friends' calendars as well as your own, making it far easier to schedule things hang out times, mentoring sessions, meetings with your profs, etc.</p>
