I want to get a new laptop and have narrowed the field to these two computers. Now I'm stuck and don't know which way to go. I think with the Photoshop software the Vaio will let me do what I want to with photos, but I like the Mac's fully integrated software. While I can see either one being a good choice, I also feel like one is better than the other and I'm just missing seeing how.
My primary goals for this are photo storage and editing, web surfing,
basic gaming, word processing and such. I'm not concerned with Vista or no because I have to learn it anyway to help my mom with her computer. I haven't used a Mac in a very long time so I'd have a steep learning curve there.
Can anyone help?
The key item that jumps out to me is the part I highlighted in
red...depends on what you mean by basic gaming. As much as I like Macs, the reality is that if you have serious level of desire to game (either hardcore gaming such as bleeding edge first person shooters like Crysis or you just want a wider variety in general), then you are better off going with a Windows computer. Granted you can run Bootcamp on a Mac and thus get Windows on your Mac which will work fine with gaming (this ignores the fact that a MacBook is not really "beefy" enough for graphically intensive games...for that, you would want a MacBook Pro instead)., but it is cheaper and easier to just get a Windows laptop if gaming is a priority.
The other functions you listed are fine on either a Mac or a Windows PC. Photoshop works just fine on Windows. Granted, a Mac does come with more integrated software for consumer level photo stuff than many Windows computers, but if you are going to the level of Photoshop, then that type of stuff does NOT come with Macs by default...it is an extra purchase on a Mac just like on a Windows PC.
Personally, I would take the Mac...but then you are NOT me.

I would suggest putting hands on both, if possible, and see how you actually like working with both of them. Based upon your post, I would guess that you will likely be happier quicker with the Sony, but you might like the Mac better eventually if you get past "the learning curve". But, the reality is that I cannot know how you will like either. Only YOU will know that.
