Working Homebased, Laptop or Desktop?

I remember posting this article on my other blog before and got a lot of feedback from my readers.  Now, I own a laptop, thanks to the help of my readers and through this buying and selling online site.

If you frequent my blog, you will know by then that I work as a BPO agent, a medical-slash-legal transcriptionist in particular.   Most of you might think that I work homebased, but I'm not.  I work in an office environment.

Last year my mom left us, so I have difficulty managing my time between work and family.  I also began to have financial difficulties.

During those moments, I started thinking of doing something on my own, a homebased job.  I first researched on the ups and downs of working at home and the things needed to start with.
First thing on the list, of course, is a desktop computer or a laptop.  I do not own one now, guys, so please help me weigh those two.

With nothing to lose, I searched the net one day for cheap laptops, and by chance, I landed on AyosDito.Ph.  I find it easy to browse the items because the sellers have pictures of their items, and just below the products you can view the prices immediately.  I always look first on the price (price matters even when I go to grocery stores, haha).

Would it be a laptop or a desktop?  Which do you think is more comfortable to work with for a homebased job?  I need your expertise, techie readers.  Help me in my entrepreneural journey.

Though I do not earn that much online yet, the thing is I enjoy it.  I still work in the office but working online has become more fun.
