I'm thinking I can get more done at home (I used to work at home and loved it) and am trying figure out what to buy. I will be designing with Solidworks but also need MS Office. My assemblies aren't large - maybe 20 parts tops. I'm considering a laptop but I'm just not convinced mobility is necessary. I'll pay a bit more for the convenience though. Any suggestions on the latest, greatest, and cheapest? I'm old and tired and just don't have the desire to keep up computers. I'm not really interested in building something. Dell? What model? TIA.
