My history with MDG is a complex one.
It all began in November 2002. We decied to replace our computer from 1997, which had 200mhz pentium processor, 32mB of ram, (yuk). I saw an MDG ad in the local paper (never heard of the company before then) for a Pentium 4, 1.7Ghz, 80Gb hard drive, 512 MB SDRAM, cd burner, 17" Monitor, free all-in-one printer, keyboard/mouse, sub-woofer speakers, and a free webcam... all for a price of $999 (i think). And in those days, that was a great deal - although we had to wait 6 weeks to pick it up, even though we paid for it up-front ...dad wasnt to happy about that. I still have that computer in the basement, it has never had any serious problems, but a few minor ones. The floppy drive and the modem wires were a bit loose after a few years and didnt work so i had to get them looked at by the local computer store. The Cd drive stopped working so I had to buy a new one, and I added 256MB more ram about 4 yrs after the purchase because I received a low memory warning from windows. But again, no major problems - it's an OK machine (although the monitor squeals sometimes, and they *forgot* to give us the free webcam when we picked the system up so i had to go back there and get it, but they were very nice about it, didnt even want to see a reciept or anything... then again, it turned out to be a piece of junk camera, instructions were poorly written, etc).
So in 2005, 3 yrs after purchase, I was still a big MDG supporter. My brother was going away for school so I told him to get a laptop from MDG. He paid $1200 for laptop with 1.4Ghz, 30 Gb hard drive. Today, 3 yrs later, that notebook is a piece of junk. The hard drive burnt out in 1 year, and the Wireless no longer works...had to buy him a usb wireless adaptor. The keyboard buttons get stuck. And I cant remember what the ram was when we bought it, but right now windows says it has 194 MB of ram, which makes the comp VERY slow. I installed puppy linux on it and now at least it runs fast (windows of course is still slow). So after that experience i became more hesitant of MDG. (plus when we bought the laptop we got a carrying case to, but after we paid for it they said they were out of stock so we had to wait a week to pick it up). This was an Acer Travelmate laptop to be fair, but MDG was the company that sold it to us.
In 2006, I decided to give MDG one last chance. My sister was now going away to school. I went to MDG's website and was interested in there horizon book for $599. I printed off the ad and went to a new MDG that had opened up closer to home. The salesman took one look at the paper and then started telling me why this computer wasnt good. He wanted me to buy the more expensive one. When it became clear to me that this guy was worse than a used car salesman, I said I'd think about it and left - you cant con me! I went back home, looked at computers on futureshop and bestbuy's websites and the next day I bought my sister a Toshiba Satellite 1.84Ghz, 1GB Ram, from Best Buy. That computer works great today, 2.5 yrs after purchase. That was it for me and MDG. The Computer they sold my brother is a piece of junk with hardly any ram, and they tried to con me when i went in there the last time.
MDG was once an OK company, offering cheap prices with lots of extras. But today they make substandard machines, have poor customer service, and are no longer competitive in the computer market, as I have seen many better deals at places like The Source and Futureshop compared to the stuff MDG has on there website today.
Bottom line, I'd avoid MDG today, and if you do go, be cautious and do your research, you may find better deals elsewhere. Look at the RAM, the type of processor, the L2 Cahce, the Bus speed, and so on. Or better yet, buy a MAC, if you can afford it
As for me, I bought a Sony VAIO laptop this summer, 2.0GHz Intel Core 2 Duo, 3 GB ram, 225GB hardrive, lcd sceen, etc. from Best Buy ($799) and I love it... even Vista too lol - never even considered going to MDG.
