It almost a year of adsense. I have adsense for about 10 months and it is simply great. Can wait to check my stats in the morning :). However Adsense will be great if it can.
1) Provide alternative payment solutions (Wire transfer, paypal etc)
2) More details on if we can do double serving and ad should not be repeated.
3) Option to include css with adsense and complete control over the ad (currently for premium publishers)
4) End of days stats to be mailed or smsed
6) Delivery of cheque via International courier (Fed ex, bludart etc) It will be ok if they would cut the charge from our account.
7) Early notification of the next Google update :-)
