I've been using Gmail for a little while now, and I have to say it has my seal of approval. Google has done a great job of holding true to their original intent of starting Gmail - having so much space you never have to delete anything. As someone who receives buckets of email, it's nice to know it will always be there. Previous to Gmail, my account only allowed 100mb of space. It was getting to point where I had to completely clean out my box every other week. Not only was this a waste of my time, but I would bang my head against the wall when someone else referenced the email and I couldn't go back.
Now don't worry, I'm not completely in love with the program. There's one item I would fix. Well, not really fix, but add. As a visual person, it would be nice if Gmail had a way to highlight my messages with different colors. That way I could quickly tell who it was from or which account it went to. I realize they already have this with their label and filter system, but I'm a visual person. I suppose knowing Google, if that slows the program down one fraction of a second, and demand for it isn't huge, it'll never happen.
That's okay. I still use and like the program. I enjoy chatting with my family and friends and look forward to seeing what they put out next.
