I currently use an i5 SP3 at work which is a great machine. Im going to hold off unitl Oct to see if anything is mentioned about a SP5 release. The ASUS Transformer 3 Pro has also caught my attention with all of its ports. I do not know when it is to be released though? Will be interesting to see if an SP5 comes out and what it might contain. Sometimes the latest and greatest isnt always the best though.
