Therapist Software Recommendation For New Computer?

Recommendation for new computer? - therapist software

I have recently bought a new laptop Toshiba Satellite A 205 at Best Buy. I do not know what they are buying. I have about $ 1800 for the team sypware, software and / insurance. I have 14 days to trade. Recommendations? If I stay with this team or switch to a Mac, Sony, HP and Lenovo. What are your favorite and why? That's what I need on a computer: Do not bring (the image of the full version, only the expression), Word, Excel, PowerPoint and QuickBooks accounting software. I do not play. I am a speech therapist for Word documents, Internet, etc.

Thank you!
