Looking at my Sony Vita charger it supplies 1500ma and looks like it's pretty much the same charger Sony uses for the T1 so I'll presume the T1 can handle it.
Convenient and potentially faster to charge I'll agree but holding more charge I still have a problem with, while stranger thing's have happened I still believe the slower a battery is charged the more effective it is.
My comments are based on the specifications for this type of battery from the manufacturers and designers of the batteries... try googling Li-On or Li-polymer specifications or similar and you can find the ACTUAL details and recommendations for them rather than anecdotal "evidence"
