Emot
- Känslig för fingeravtryck...
- ...som är svåra att få bort
- DVD-enheten är installerad i vinkel
- Inga underhållsmöjligheter utan att plocka isär
- Alla gränssnitt framtill
- Ej bakbelyst tangentbord
- Medioker TN-panel
- Olämplig för spel
Egentligen är det bara priset på Acer TravelMate P257-M-56AX som måste ner lite för att datorn ska få vår köprekommendation. Ca 7 000 kr vore acceptabelt enligt oss, och förmodligen hamnar priset där under de närmaste månaderna.
Testenheten var en oansenlig men solid och inte bara tekniskt imponerande kontorsdator, med bara en riktigt svag punkt: den mediokra skärmen.
Utöver den perfekta temperaturhanteringen lyser datorn med sitt minst sagt ambitiösa utseende, välbyggda hölje, mycket trevliga inmatningsenheter, tyst och sval drift, tillräcklig batteritid och mer än tillräcklig prestanda. Användare som vill spela kan istället välja t.ex. Lenovos Z51-70 eller en annan (dyrare) modell av P2 med ett GeForce 940M.
