I've recently made the move from SW to WW, and I have to say I'm loving it.
Yes it does take a little while to get used to pointing everything, and there are occasions where I feel a little more hungry than I would have on SW, but I think thats because I was eating a lot(and I mean loads) of pasta and rice on SW.
Plus its easier to deal with feeling a little hungry when you know that you can have a treat of whatever you like when you do eat. I was missing a lot of my favourite foods on SW and now I can have everything in moderation.
Having ready meals etc can be handy to. I don't eat them all the time, but I like the convenience of being able to throw one into the microwave if I've been working late, and know exactly what points they are. They're not very big, but they're easily bulked out with veg!
I do it all online to ( I was doing SW online as well ) and find the site easy to use.
Go for it, you'll never look back!
