The thing is, every platform both software and/or hardware has it's advantages. You give me your budget and tell me yours needs, and I will give you suggestions what kind of hardware and/or software and/or wifi you should purchase.
Or perhaps upgrade your current computer ? Or maybe not have a computer at all and go tablet only? And maybe purchase something that lasts for 3 years? It all depends on your needs.
This gig will answer all your pertaining questions (and save you a lot of time and money during purchase). I will do the research for you. Been a hobby of mine for about 20 years.
