1) Assuming this is a SaaS or other software/web based offering I probably don't need to know if you're a solo entrepreneur or a multinational. So long as your website is professional you can easily appear to be at either end of the scale (and it's funny that you do often get solo's acting as big corp while big corp wants to appear botique). The point is you can brand your offering in a way that doesn't scream solo developer.

2) If what your offering is something that involves sensitive data, financial stuff or something I need to sell on to another company I'd probably be more inclined to go for a more corporate setup so if things go bad it's not going to reflect so badly on me.

3) I try to avoid getting locked in to anything so regardless of whether your solo or a corp I'd want to be confident that I'm able to continue if you/the corp drops dead.

4) As someone who has generally been a solo developer (although freelance rather than managing to get my own 'product' out there) I've seen first hand the +/- of this. On one hand my clients appreciate that they can pick up the phone or send an email and speak to me who has inside out knowledge of what they're talking about, I'll work my arse off because I've got a lot to lose. However that might be impacted by me having a bad day, a holiday, being sick, a new shiny project or just a general lack of motivation.
