Apple iMac

Apple has always fascinated people from the starting of the company, when it was founder in 1976. It made its way as a computer maker to high end Ipods and then came the top class Iphones.
But iMac's were the only products of the company that have seen great improvements and great selling of the product. A month or two ago iMac 21.5 inches and 27 inches was revealed,  Apple has put some serious engineering efforts into this, with rigorous techniques like friction stir welding. But the only thing that matters here is the price tag. The 21.5 inches comes in Two models - The Base and The Top End with price of $1299 ( INR 85,900 inc. ) and $1499 ( INR 99,00 inc. ) respectively.
Similarly the 27 inches also comes with two models - The Base and The Top End with price tag of $1799 ( INR 122,900 inc. ) and $1999 ( INR 134,900 inc. ) respectively.
Today I will review the 21.5 inches one ( both the models ), here it goes ...

• Multiple Thunderblot ports 
• Amazing performance

• More power-efficient hardware cooled by a single fan ( which is better for a desktop PC

• Users are not able to swap to newer CPU ( in future )

• Speakers are not upto the mark
• No optical drive

• Heavily priced

Conclusion :
Although there is an option b/w Base and Top End model of thw 21.5 inches, I would prefer to buy out Base Model because even at the default configurations iMac should satisfy all the computing needs of yours. But, if your looking to shell out more then go for the Top End one. Even with the great performance, I would consider buying a Window's computer instead, because if offers more flexibality and more friendly user interface with less price.
Nobody buys a Mac to use it just as a games machine, and if you treat the iMac as a general multimedia and entertainment system then it’s gonna hard to beat. The slimline design is superb, as is the improved display, and the engineering quality is truly in a class of its own. But the problem with this one is it is heavily priced, I am not able to understand for what the company is charging this much!
Still its upto you go for the Brand Apple or you have a better choice in the market out there!

• A little over priced

                                                               Conclusion : 

With Windows 8, which is also compatible with tablets, most of the makers are more or less willing to develop convertible laptops. All ultrabooks with Windows 8 share the same specification at press time, every Ultrabook featured the same base processor - hardware and design will be the differentiating factor for the next half year, and possibly longer. That means aesthetics, batteries, input device, and other intangibles will matter more than anything else.
If you see overall, its a great ultrabook with all the features in it a buyer needs, but if you don't want ultra-convertible laptops, then you want to consider others out there in the market.
