It's pretty stupid to pay a hefty penny just to move to an operating system that removed the features you've recently deeemed 'unnecessary'. How about you stop finding an excuse to spend money and use what you have? What does a mac have that a PC doesn't for webbrowsing? your arguement would be a lot more compelling if you were just going into computers but you're not so you're just looking for an excuse to spend money.. Your system is perfectly fine for webbrowsing and doing other 'light tasks' so why bother trashing what you currently have for something else to do the same thing?
You know what this is analogous to?
Example:
I drive a BMW M5 2002 model, it gets 25/22MPG, it's a really great car, nice features, runs fine, gets me laid and everything but I'm considering getting a honda civic. I saw a honda civic the other day and it really impressed me, has some cool features, gets 30mpg, and because I'm married now and I don't drive fast like when I was a kid, I'm thinking of selling my M5 and getting a civic instead as thats all I really need anyways...
