Nice. Actually, that's probably the best idea. I missed before that you said you will use it mostly for browsing. The infinite scroll wheel is awesome for that. I have a G900 (the older version) exactly for that reason.

Also, what I might not have been clear about is that while it's not a "great" palm mouse, it's still a very good one. I use the G900 in a mostly palm-like grip (just my index finger is lifted a little), and I find it more comfortable than most other mice. (Though, I also have particularly RSI problems than make true palm mice uncomfortable for me.)

It's better as well for MMOs than a G703, and better for FPS than the MMO mice.

The G703 is definitely a good one to try. I will actually change what I said a bit and say you might also like the Corsair Dark Core if you want a more MMO-specialized wireless mouse.
