I was debating with guys about necessity of SSD for me.

I'm Salesforce Developer. My tools are Eclipse, Firefox/Chrome, Git. Eclipse does only editing files, saving them locally and sends them to cloud, gets them back. So no code compiling or heavy servers on my local machine. I start Windows 7 on Monday and restart it when new updates are installed and Windows need to be restarted to apply updates.

Basically, I don't care about how fast apps are starting. I don't care about temperature, energy consuming, noise, etc. I have Dell laptop with i5, 16GB RAM and 2.5-Inch 500GB 7200RPM SATA III 32MB Cache SATA 6Gbps HDD. I saw, that my PC uses max 5-7GB of RAM. So I thought, why do I might need and SSD when I have free 10GB of RAM.

So, guys said, that all apps read/write stuff on HDD even if you have a lot of free RAM. Is this true? How to check what is written/read to/from HDD during my work?

EDIT1:

I don't use swap or page file in my Win 7 64.

Yes, in general, that's true. How much and how often will depend almost completely on the specific application(s).

Not to mention the Page File usage (which SSDs are awesome for, BTW). For more specific information on that, perhaps check out this other SU question and answers:

Why does Windows 7 use the page file when there's free physical RAM?

Windows 7's in-built Resource Monitor will show you live disk I/O activity. Look at it, and judge for yourself.
