I am not a fan of Gmail, I don't like the web interface or the way that you have to manually delete the emails as Outlook/Express won't delete them even if you set it to do so.
That said, I have a gmail account and it seems to be 100% reliable compared to my other email provider (Btinternet) and as for Telkomsa, they're a joke. Hotmail attracts too much spam and scams, and again Gmail's filtering is the best.
If I didn't have my existing Btinternet accounts and were setting up from scratch, I'd go for Gmail. The only problem is that I use it professionally and some clients might think that a 'freemail' account doesn't look very professional.
