[citation][nom]cadder[/nom]For those prices you can buy a really, really good business class computer from Dell or Lenovo. My TWO YEAR OLD! Dell E6500 still has better specs than the much more expensive entry level 15" MBP. And even though it only has Vista Business, it has a much better OS than the entry level MBP. (And I also own a Mac running the latest Mac OS so I know how the OS compares.)[/citation]
Don't know what spec sheet you are looking at, but perhaps you should do some research before posting...
Your Dell E6500 uses a Core 2 Duo with a max speed of 2.8Ghz. The new 15" Macbook is *quad* core at 2.0Ghz and can turbo boost up to 2.9Ghz, supports Hyperthreading, uses DDR3 memory, etc. The newer processor is newer technology and can't be compaired by Ghz speed difference alone!
Both support the same amount of RAM, although the Dell uses DDR2 memory. As for graphics, the entry level Macbook uses the 6490M. Even it's little brother the 6370M(also named the 5470) beats out your Dell's Quadro NVS 160M(see:
http://www.notebookcheck.net/NVIDIA-Quadro-NVS-160M.11908.0.html Mobility HD 5470 is 76% faster based on their benchmarks).
When it comes to the OS, the OS is only as good as what you do with it. So to say OS X is not as good as Vista is an opinion, not a fact. I had Vista Ultimate(now have Windows 7 Ultimate) and prefered OS X to either it or Windows 7. OS choice is mostly opinion, not fact. For instance, I think Linux is better the Windows, but Linux is limited when it comes to gaming and such. It all depends on what you are trying to do with the OS.
And before anyone starts calling me a mac fanboy... I've only owned one Mac, and don't actually even have it now(had to sell due to financial issues...held value very well and was able to resell for quite a bit, lol). Their products do tend to be pricey, but you do get what you pay for. If you compare laptops spec for spec(and not just take them at face value like cadder has), then you aren't really paying that much more then a Windows based laptop. Also, when it comes to OS X upgrades, $50 to go from Leopard to Snow Leopard was MUCH better then the couple hundred I had to drop to go from Vista to Win7.
