Should You Buy an iMac

I have had the opportunity to use an iMac for the past week, and I have to tell you that I was quite impressed. I’ve long been interested in alternative desktop Operating System (meaning Not Windows) and once worked for an entire year at home with Linux (I’m now running WinXP). The iMac has been getting a lot of press (and has cute commercials) So I jumped at the opportunity to test one out.
 
Here is what I Used

Hardware
iMac with Intel 3.06 Ghz Core Duo Processor, 24″ Monitor, 320 Mb HD, 4GB RAM Memory: Cost $2499
Additional Software
Microsoft Office For Mac: Cost $399
VMware Fusion (To run windows with): Cost $79.00
MS Windows XP Professional Edition: Cost: $289.00
 
(The 24″ 266 version is one of the higher end versions, but some start at low as $1199)
As you can see I installed windows on the machine as well, using a VMware Fusion , which allows you to run Windows Applications on the iMac. You will have to install windows yourself within the VMware Fusion product. (There is also another product called Parallels which also runs Windows) I need Internet Explorer and  a few other applications that are not available for Mac.
 
What I liked
1. Speed. This machine was fast. The OSx operating system is optimized with the hardware, and it has a lot of horsepower. Everything ran faster than my other machine. (To my Windows machine’s defense it is only running a single core processor) . I never waited long for anything on the machine to happen.
2. Users Desktop Interface: Its clean an uncluttered and you can setup 4 different work spaces ‘Screen’s and customize your windows by task, and easily move from screen to screen. It has a ‘dashboard’ feature, that lets you setup ‘widgets’ (mini programs) that pop up over your screen so you can check your stocks, the weather, and news. It also has an application called Expose that brings all of your open programs to the front so you can see whats running in a workspace, and find the application that you need.
3. Simplicity of the hardware. the iMac consists of what appears to be a flat screen monitor (actually its the entire computer) and, a wireless mouse (optional) and a wireless keyboard(optional). It only used one electrical outlet, and has built in wireless so you don’t even have to plug in a network cable if you don’t want to. (it does have Ethernet, USB, and Firewire ports on the back of the  ”monitor”). There is a slot on the right side of the “monitor” for CD’s  and that’s the whole thing.
3. Applications. Office for Mac works almost exactly like Office XP for Windows. There was almost no learning curve. The Safari browser is easy to use. The version  of an the iMac that I had has a camera in it so I can video chat with other iMac users. 
 
What I didn’t Like
1. Cost. Even if I bought he base system (Starting with the lowest end model, with Windows compatibility and MS Office) I still couldn’t have the setup i need for less than $1800. I could easily get a workable equivalent Windows PC (1GB ram,250GB HDD,20″ Monitor, XP PRO) with MS office Small Business for less than $1100.
2. Setting up and running two operating systems. You have to install, and setup, and use  windows as well if you are going to need it for any applications

 

What I’m not sure about
There is no expandability once you get the hardware. If you need to have the computer fixed, you will have to go to apple. All of the hardware is proprietary. While I don’t think this is a big problem. If they system fails you are at the mercy of apple.

 

My Recommendation
If money is no object. I think this a great machine, its fast, cool looking and has great features. If on the other hand you are on a budget, you will pay quite premium for to have the apple.  You also are going to have to deal with a windows compatibly package, if you run the chance of needing a windows application or even windows Internet explorer compatibility.

4 Free Ways to Create PDF Documents


 The PDF (portable document format) document has become a standard for distributing documents electronically. Almost anyone either has a PDF reader. PDF’s can contain images and hyper links, but cannot be easily edited, making them perfect for everything from contracts to marketing materials. Many companies sell full fledged applications for editing and creating PDF’s, however, if you just need create a basic document in PDF form, I have found 4 good free solutions.
 
More information on the first three choices can be found in my post Save hundreds of dollars with Free Microsoft Office Alternatives
 
Web Based Tools
 
1. Zoho is a web based office suite that allows you to create documents & spreadsheets, save them on the web, and export them to various formats including PDF. (They have a choice to export  presentations to PDF, but it gave me an error when I tried it.)
 
2. Google Docs is also a web based office suite that allows you to create document, spreadsheet and presentation and export them to PDF. 
       
 
PC Based Tools
 
3. OpenOffice.org is a free office suite that installs on your PC. It includes a word processor, spreadsheet, and presentation application (and more). Any of the documents that it creates can be exported to a PDF.
 
4. Primo PDF is a free pdf printer application. It allows you take a document from any application and convert it to a PDF from the print menu with a ‘printer’ that creates a PDF document. The nice thing about Primo PDF is that it lets you make a from any application that you can print from (Web Browser,Drawing, etc) not just a specific application. Primo PDF also allows you to set security on the PDF so you can’t cut and paste or print the PDF.

Secure your #$%** Wireless Network, Please !!!


I Know I already have done a post on wireless security but I’m doing another one because of my iPhone. One of the nice features of the iPhone is that you your can connect to a wireless network to surf the web, and you can set it to ask you to join wireless networks when it finds one and guess what?  you cannot believe how many open (unsecured) wireless networks I can see (without even logging into them). Frequently, when I tell the network owner about this a get one of the following answers.  
“No one can get close enough to connect”     
“There’s nothing on my network worth accessing”     
“It’s too much trouble”

Let me deal with these excuses:
1. No one can get close enough. Yes its true.. for reasons nobody understands, in your house you have to be right next to the wireless access point to get a strong signal, but the specified maximum distance for wi-fi is just over 100ft, and I guarantee that somewhere (that you are not)  its getting that range. That may be your neighbors house or someone’s car (with a laptop) across the street. Besides, if the hacker is at all serious about getting “free wi-fi” he probably has an antenna that significantly extends his range. So unless you live in the middle of 50 acres of land surrounded by barbed wire, and patrolled by dogs, someone can get your wi-fi signal.
2. There’s nothing on my network worth accessing. Let me list the stuff on your network worth accessing.
    A. Bandwidth – Someone else can download files, movies, etc and slow down your network
    B. Your Networks Identity. If I want to access illegal sites or download illegal files (Pirated Software, Music, etc) I can use your network, and then the download will be traced to you not me. When the RIAA or FBI, or whomever, shows up at your door, you are going to have some explaining to do.
    C. Your Network Communications. Even if you don’t have any computers on your network but just hook up with a laptop, the somewhat savvy hacker can capture all of your  you send over the network (like logins and passwords to your banking site).
    D. Anything on any computer on your network. Once a hacker has access wi-fi connection, they can at their leisure find any weakness, or un-patched security holes in your network, and steal everything other piece of information of  of value on your network.
3. Its too much trouble. See #2 above
So please read this post (or someone else’s if its better) and get your network secured, while wireless security isn’t the greatest, and it cannot guarantee that you won’t get hacked, It will make it easier for the hacker to hack your neighbors unsecured network instead of yours.
Please Note: It is illegal to connect to someone else’s’ network without their permission. I only connect to wireless networks with permission.
