I think that home users should upgrade. I am a tech all day long i see people comming in with mid lvl P4's with 256 - 512Mb ram. People these days should be using a Vista box with a Duel Core and atleast 2gb ram. Now for business it is not worth it to change yet. It would cost way to much to buy or upgradeall thre pc's to run Vista. Also from what i hear the new Windows isn't going to launch until around 2010. Not so much around the corner.
I hear '09.
One computer or a hundred, makes no difference as a second isn't added unless it is a benefit. Except they can probably buy bulk cheaper than I can buy one unit(Going to give me a deal or am I shopping elsewhere?).
You forgot the graphics card. And it is still too expensive for me. I don't have the funds available that a business has nor can I write it off as an expense, making it that much cheaper for the business to do so.
There is no economical benefit to upgrade and switch to Vista, else business' would do so. Meaning you will be no more productive on Vista than you are on XP.
The benefits go to MS, hardware companies and support.
One graphics card for me $800.
One hundred graphics cards for Company $80 000? More like $72 000 max. (10% off)
$72 000 expense X 40% tax rate is $28 800 in tax savings
72000-28800=$43 200
One graphics card for company? $432.
If it is worth it for home user, why isn't it as well for business at almost half the cost?
