I have had a Gmail account for some time now, I didn’t particularly need another webmail account (or any type of email account for that matter - I have too many already) but I was interested to test drive it, just to see how Google had implemented this age-old web application*. I wasn’t disappointed, gmail is fast and lean and I quickly started using it ‘in anger’. No problems or even improvement suggestions, it’s fast and responsive and managing long conversations is a breeze. The 2+ Gb of online storage has been useful too 
I just noticed there is a new logo, “Google Mail” instead of “GMail”. This is to do with a trademark dispute in the UK over the Gmail name. Whatever. I’m not about to change my address.
Another thing I just noticed is the number of invites I can issue has gone up from 50 to 100. Like there is anyone left in the world who doesn’t have an account already….
* I’ve had a Hotmail account since about 1995 - before they were bought by the beast from Redmond. I even managed to get a good address, before everyone with the same name as me snapped them up! I hardly use the account now, it’s basically been spammed to death.
