I am pretty new to this whole thing, so please only take my oppinion with a grain of salt..
Well when the intel transition was first annouced, i thought great, atleast apple is still supporting its PPC customers, and will make this transition nice for many. With the expected intel products in the summer (the first one), i thought how nice for the ppl who have recently purchased new macs, so that by the time there's get a bit bogged down 2-4 years, they will have a wonderful assortment of new intel macs to choose from. Now it seems to whole process is a bit rushed, i am almost positive by the end of this year, the intel switch will be complete, with most apple apps being run on their own rather than rosetta. I personally do not think that beyond the next mac os, ppc customers will get another 2 os's out of the macs. It is possible, but i am almost positive that the next OS will be the last for ppc imo. Which is somewhat okay for me, cause by that time, when w.e. comes after leopard is out, i suppose for anyone who has purchased a mac within the last year (ppc) it will be time to upgrade anyway, 2-3 years of use is good for a comp...
obviously u can keep the mac longer than that, but for ppl who want the latest OS, i am talking about them, or me.. so yah, a bit disapointed that the switch is going so fast, but not so much as i thought i would have..
I just tend to look at it this way, in 2-3 years, im positive everything will be back to normal, and fully in tune with everything, so as much as id love to have all this bootcamp, etc.. im glad that when it is time for me to try all that out, it will be at its best, and not beta, etc..
