I just bought a brand new M505 series Toshiba Satellite 3 days ago for $579 (had a thread about it under Netbook run photoshop or Illustrator). Most of the spec is the same as your E105 series except for the CPU. Mine was AMD Turion X2. I'm loving it.
I'm not sure how much you bought yours but on that link its almost double what I paid for my M505 so that gives you an idea...
Rest of the spec for the M505:
4 gigs of RAM
ATI Radeon 3100 GPU
320 gigs Harddrive
VISTA Hom Pre.
Edit: Just noticed you wrote a post on my thread
The M505 handles Adobe Master Collection CS3 with no problem. Lighting fast with no issues.
