No! I use it constantly because in normal gmail I can only have like 5 versions open ( I have a lot of tabs) before my mac pro explodes. But for HTML gmail I can leave emails open for reference without exploding.
I use it so often, it loads so fast for multiple email accounts, instant refresh, it was so good
I'm surprised I haven't heard this argument more. It's an absurd amount of javascript.[0] I'd think the effect on battery life would be at least as important to many people as the bandwidth of loading it.
[0] Just checked, and I get 8.22Mb of heavily compressed JS to load Gmail!
