Congratulations on your scholarship!
Don't want to raise the hackles of anyone here in the Acer forum, so in an attempt to get the facts, I went hunting around to find specs on the C111TC-G

A casual comparison
I saw an Acer C11x a few weeks back. I put my TC1100 (Pentium M) beside it and did some informal comparisons.
The most striking impression for me was the difference in the viewing angle. The HP was viewable, usable over a wider range of viewing angles. To be fair, this was in a retail store with very bright overhead flourescent lighting. This was a most unnatural and unlikely situation for normal Tablet PC use.
