Went through the same you're going through now. I have two phones for business, one for rough job-site use for my phone calls, and another (Galaxy 3) for my emails, dropbox, evernote, weather, etc..
I thought I needed a tablet. So cool, compact, thin, fancy and all that so went out and purchased one. Returned it the same day! Not for me and it wasn't what I needed.
There's nothing like a real computer at your finger tips. Ordered a Dell 14" laptop about two months ago and never been happier, and happy I didn't get a large screen, the 14" is perfect for portable use and I have all my programs with me.
also stayed with Windows 7 Pro, I love it on my desk top and now have a portable with it.
