Conclusion
Acer has created a very interesting Ultrabook with the Aspire S5, which they have clearly positioned above the existing Aspire S3. The retractable connectors are a fun gimmick, but the presence of a Thunderbolt connector is even more exciting. It's a shame Acer did not include more connectors, such as a network and VGA port.
Another unique feature are the dual SSDs consisting of two 64 GB MSATA SSDs in RAID 0. Since small SSDs are comparatively slow, you don't get extremely high transfer rates. The version with two 128 GB SSDs probably is significantly faster in that regard.
The Acer Aspire S5 has more connectors and is lighter than the Aspire S3, aside from having the SSDs. It's too bad then that nothing was done with the display, which preferably should have had a resolution of 1600x900.
The Acer Aspire S5 with Core i5-3317U/128 GB SSD costs an average of £999.99. The version with Core i7-3517U/256 GB costs an average of £1249.99. Both come with a factory warranty of 1 year.
