Since the XO-1.5 casing and connector positions is the same as the XO-1 and generally seems to use very similar components (same battery, same screen ...etc) it seems possible to make the XO-1.5 baseboard compatible with the XO-1.
This would mean that the huge number of XO-1s deployed (more than 100K G1G1 owners and 900K units in country projects) could be upgraded into a much more powerful machine for a small cost.
The XO-1.5 will have similar performance than todays low power netbooks. Admittedly, it will not be the fastest in the leage but it will be in the same category.
This upgrade could transform XO-1 machines into completely usable, responsive browsing devices with acceptable Flash and Java speed.
If anyone has information about this possibility, please let us know.
