Windows moble 6.1 OR 6.5 OR 6.5.3

[Guest ddipper]

Hello all,

i have done comaprison between windows mobile 6.1 and 6.5 between my htc kaiser and touch pro and i was wondering if the 6.5 os may be slower for our devices despite the upgrade in user interface.

If a 6.1 rom is faster than a 6.5 rom why are all rom developers producing 6.5 roms?

Despite the lack of touch friendliness in 6.1 roms, are there any other advantages to a 6.5 rom other than features an average user may not use?
