I'm considering getting an iPad to make myself more mobile. I am a starting out web designer and do not have he budget for a MacBook pro or 13 air. I do use photoshop and hand code my websites but I am not heavy into graphic design. I am hoping an iPad would allow me to go outside and work in public areas. Are the wire framing apps any good? Does a notepad or coda type app exist? Or Should I just keep dreaming about being able to work outside until I can afford an actual laptop?
