When Acer recently demoed their 10 inch Aspire One netbooks, many reviewers were pleasantly surprised to discover a netbook that could boast an uptime of nearly 8 hours while under moderate use.

In the earlier version, the second SD slot was there to hold a flash memory card that would be more-or-less permanently housed in the netbook to augment the 8GB or 16GB SSD. According to Acer’s spokesperson, the new version lacks that second slot “due to the increase in standard storage sizes
